Color shift in save for web

Help!! Yelp! I have followed the directions in previous posts for fixing color shift when saving for web. I switched my monitor to gamma 2.2. I chose sRGB in assign color profile.
The colors still look washed out!
I am using CS4 on the Mac.
What am I doing wrong?

You are using "assign" instead of CONVERT to sRGB. In addition, accurately calibrate your monitor often and regularly. Even the cheapest hardware calibrator will give superior results to eyeball calibrators.
See the FAQs in the Photoshop forum for your platform, Macintosh or Win.

IBooks author color shift with "Save for web devices..."

Hi! I'm a web developer and I'm learning to use iBooks. It's a really easy tool, but there is a problem with color management wich is driving me crazy. This happen when I export images from "Save for web devices..." from Photoshop, then drag it to iBooks author.
As I do for web development, I do this:
1) Configure photoshop Color Settings to work with "Color Monitor"
2) Remove any color management from my document
3) Proof Setup > Monitor RGB
4) Disable Proof Colors
5) Use "Save for web devices..." with ICC profile and sRGB unchecked
The exported JPG looks fine everywhere... Photoshop, Preview, Safari, Chrome, FF... but looks washed out when I drag it to iBooks Author. Why?
I solved this issue converting to sRGBIEC61966-2.1 profile and checking ICC profile when "Save for web devices...", but I'm not confortable with this workaround because I'm not sure about what I'm doing exactly, and I am not sure if this images are gonna look good on any device (I only own an iPad 3).
Somebody know a best method to deal with this?
Thanks!

Hi KT. Thanks for your response. I'm already using this formats. Anyway, the problem occurs within iBooks Author interface. I mean: I can see the color shift (or washed out...) at iBooks Author at my computer screen. Of course, when I test it on iPad it also looks bad.
It's incredibly strange because the JPGs I'm using looks fine everywhere else except iBooks Author.

Color management in Save for Web not working

The Save for Web dialog box in the CS6 Beta is ignoring color profiles, so color is not managed. This has not been a problem in previous versions.

The saved output is just fine. I was referring to the images in the Save for Web dialogue
I just checked my settings. CS6 apparently changed my Preview setting from "Use Document Profile" to "Monitor Color." It also changed my Metadata setting. It should not do that!
Restoring the correct Preview setting solved the color management problem, but ONLY for the Preview image. The Original image is still not color managed.
I'm on a wide-gamut monitor, so sRGB images come out looking garish if there's no color profile embedded or it's ignored. That's what's happening here with the Original image in Save for Web. I imported an sRGB image with profile embedded, and it looks just fine in Photoshop while editing. Then I went to Save for Web, with the settings Embed Color Profile, Convert to sRGB, and Preview: Use Document Profile. The JPEG preview too looks just fine with these settings, but the Original looks garish, showing a lack of color management. The color in the two views is showing as completely different, though they both represent the same image with the same color profile embedded.
Going back to CS5, the same image is properly color managed in both Original and Preview. Both images show identical color, as they should.

I also have a color problem when Save For Web

Using Photoshop CS4 and I also have a problem when I use the "Save for Web & Devices" My colors also get bleached. I found a thread with the same problem but on Windows.
As I have a Macbook Pro I can not change my monitor settings. In the SFW I check "Convert to sRGB" but it make no difference. I also tried to convert in the menu before using SFW. So I need some help here.
Here is a screen shot on my screen: http://www.scancyp.com/dump.jpg

Also I was wondering why?
You need to calibrate and profile your monitor regularly and often
First: Because monitors can and do drift. In CRTs all kinds of electronic components and the phosphors themselves age; in LEDs and LCDs the back-light illuminants do; etc.
Second: Monitor profile files can and occasionally do get corrupted.
I validate the calibration of my monitors practically on a daily basis.
If you don't have an accurately profiled monitor at all times, your work is wasted.

But it's a whole science to calibrate the monitor without a hardware calibration kit. I had a look at SuperCal as you suggested, but I am afraid it's gona be too complicated for me as I think it's hard enough to calibrate with the Apple calibration tool.
Even the cheapest hardware calibrator puck will give you superior results than any eyeball calibrator. That said, SuperCal is a tad better than Apple's built-in eyeball calibrator, though nowhere as good as a hardware calibrators.
Personally, I detest laptop screens and categorically do not consider a MacBook Pro a suitable machine for serious color work. For this reason, I cannot in good conscience insist on your buying a hardware calibrator.
Laptop screens can be nearly impossible to calibrate accurately.

I have made a new screen shot with my results so far. Upper left is Photoshop original. To the right the SFW and lower left the preview result. The SFW result still don't give me the colors I want, but as I said: closer then before.
Screen shots from an uncalibrated or inaccurately calibrated monitor are worthless, always. They do not help at all, especially when they are partial snippets that don't show the whole picture.
This time around they are even worse, as I cannot see whether you rectified your Preview setting in the Save For web dialog box to "Use Document Profile", as I told you earlier:
You have to start by changing that setting in the Save For Web dialog box to "Use Document Profile".
Is your original document in a device independent color space (i.e. was your working colorspace set to such a device-independent color space like Adobe RGB or sRGB when you created the original) and is it properly tagged (does it have such a device independent profile embedded)? If the answer to any of that is no, all your work is wasted.
If your working space is set to your Monitor Profile, then your work is a useless mess. If the original is in your Monitor Profile, it's no good either. Same goes for the Preview setting in the Save For Web dialog box, if it's set to Monitor Profile, it's useless.
If you view any untagged image (any image without a device-independent profile embedded) in any Apple application, be aware that any such Apple application, From the Finder, through Preview, Aperture and iPhoto to Safari, will throw your monitor profile at your image (assuming it's really in your Monitor Profile) and it will display your image in the wrong colors, as all Apple applications stupidly assume that all untagged images were created by some fool who didn't know better.
Magooi wrote:
But now my main questions is:
Why the Original in the Photoshop SFW don't look like the original? And then why the Optimized in the SFW also don't look like the the preview? (Specially look at he shadows of the palm tree that shows in the Optimized but not in the preview)
I have no idea what all your other color settings throughout the whole application and in the Save For Web box are, what else may be messed up on your machine, or how badly inaccurate your monitor profile is. Again, your screenshot is not helpful and never will be—unless you had an accurately profiled monitor, which you will never be sure you have on your laptop, ever.
Magooi wrote:
And again, should I invest in SuperCal? It seems also to be very old.
SuperCal is better than Apple's calibrator, regardless of whatever its age may be at this point. Last time I checked, SuperCal was free. If they want to charge for it now, don't buy it. It's not worth it for a laptop screen.
On a side note, if you think SuperCal is "too complicated" for you, I doubt you're ready for Photoshop anyway, even with a better machine. Sorry, no offense meant, but it wouldn't be fair to you if I didn't tell you exactly how I feel.

Colour shift in save for web when saving on PC and then viewing on Mac

Hey peeps, I am aware of this colour shift when saving images for web. I have a designer resizing, cropping photos, and then saving on PC. He uses PC and when he sends the photos over to me on my Mac there is a big colour shift (photos are much lighte
Could anyone please explain exactly what he needs to do in order for these photos to look the same as the originals on my computer, basically no lightness shift? Any help would be much appreciated.
Thanks
Adam

Because the WWW is based on untagged (2.2 gamma) sRGB - your genius is probably sending you untagged sRGB if they were Saved for the Web (that's how I prepare my Web color).
Your Mac display should be profiled to 2.2 gamma (you are likely at the old default 1.8 gamma now if you're seeing a lightness shift on untagged sRGB)...if you want "your color" back in Photoshop, you will need to (re)Assign the sRGB profile...

Save for web problem for transparent gaphics

hi!
savng any transparent graphic in " save for web&.." the transparancy of original file is shown much more opaque/darker and so it will save in png file.
iattached file where you can see red box with 40% opaciy , but when opened in save for web it looks more like 60% opacity.
i found solutions of some problems for color shifting in save for web , but none of them solves my problem.
Any ideas?

All is not as hopeless as it seems just a bit hidden in CS 3 and earlier in CS 4 the mystry was brought to the frnt though not really document as far as I know.
The problem is simple to correct and has a logical reason why it is manifesting itself this way.
In CS 3's Save for Device and Web there is a small triangle at the top left had corner on the image display window that offers you a choice between the default and the problem uncompressed color, Macintosh color, Windows color and Document Color Profile which is what you are looking for since that is what you expect to match.
There is also the option to convert to sRGB which what the web basically displays well. Which is located on the upper right corner of the dialog also a drop down.
I hope this helps you find your way it used to drive me a bit crazy myself till I took a really close look at the dialog.

Save for web color shift - only on images smaller than 150x150px

I'm getting a color shift only on small images (150x150px or smaller) when I save for web in Photoshop CC and CS6. That's very weird as it doesn't happen to images larger than 150x150px! That issue happens with images with different measurements as well (e.g. rectangle), the small looks dull and the larger display the right color.
My Color Settings are set to "Monitor Color". Under save for web I have the following options not ticked: Embed Color Profile and Convert to sRGB. (viget.com/inspire/the-mysterious-save-for-web-color-shift)
I'm running the OS X 10.8.4 on a macbook pro, I tested that on both, Safari 6.0.5 and FF.
The squares in the screenshot were saved exatly the same way. The largerer displays the right color #FFCB32, but the smaller displays the color wrong.
I appreciate your help.

Color shift when using save for web

Hello,
I am converting my psd files to jpegs using "save for web". I am noticing that the colors are shifting from the original after saving for web. The color shift does not happen if I just convert the psd files to jpegs by using "save as". The psds have a profile of RGB1998. I am using CS3 and my monitor is color calibrated.
Do I need to convert the psd documents to sRGB first before I go to "save for web"?
The preview doesn't look any different if I check ICC profile in the save for web window. I have been told that you are not supposed to embed the ICC profile in the document when saving for web because most monitors are untagged.
Anyway I am wondering if I have to accept a color shift when saving for web or is there something I can do to get the saved for web jpegs to more closely match the original psd?
Thanks a lot for your help.

I think the reason why this question is asked often is because the FAQ entry is pretty lame and incomplete, especially for Mac users that by default have a color managed browser and by default have a screwed up rendering mechanism for untagged images.
Depending on your version of Photoshop, you can convert to sRGB before or during the Save for Web operation.

...I have been told that you are not supposed to embed the ICC profile in the document when saving for web because most monitors are untagged.
You convert to sRGB for the systems that do not fully support color management.
and...
You include the sRGB ICC profile for the systems that do support color management.
Doing both covers your bum in most situations. You may choose to omit the ICC profile if you are working on common interface graphics that do not require strict color management. The ICC profile adds a few kilobytes to the file size that are not necessary on lesser graphic elements on a web page.

Save For Web Saturates Colors

Hello,
I've dealt with this before and searched the internet for a solution/fix, but still have the problem of JPG images appearing over-saturated when viewing them in a web browser compared to the way they look in PS CS4 or in the windows "preview" application.
Here's the workflow:
Work with an image in PS CS4 (Vista) with an assigned color profile of sRGB. Use the "save for web" dialog to create a JPG (with the "convert to sRGB" box checked). View the image in Windows by right-clicking and selecting "preview," and it looks fine (looks same as it does within PS). View the same image using Firefox 3 or Internet Explorer 7, and it appears oversaturated (mosty too reddish) as compared to the original.
I've tried various permutations to the above (e.g., turning off "convert to sRGB") with no avail. However, if I convert to LAB color, and then save for web, the resulting image appears less saturated overall, even though it still appears more saturated as viewed in a web browser as compared to PS/Windows-preview.
Does anyone have any further suggestions to get the images to appear the same in a browser as they do in PS or in the Windows Photo Gallery (preview)?
thanks,
JP

What happens if you use save as? I believe that save for web does not save the color profile therefore firefox or IE might assume a different profile thus over saturated images. I have read someplace that firefox uses color profiles but I am not sure about IE.
Firefox is not colour managed by default. It has to be enabled by the user.

Photoshop CS6 save for web some colors change?

I have a picture with large area of color: #fffdfd, when I save it for web (jpg) this color is changed to #fefcfd (in JPG).
I just can not save as JPG with #fffdfd.
(was trying uncheck convert to sRGB, do not embed color profile - always #fffdfd changes to #fefcfd when save for web)
However, color #fefcfd when save for web , does not change.
Why some colors change and some not? Is it a bug ?
Window7 64bit, Photoshop CS6

Save for Web & Devices will strip some color data from the file.
Browsers aren't color managed. Most file formats on browsers assume they're sRGB. While Photoshop gives you an option of embedding sRGB to the document color space, it also strips off data that is not relevant. This is a common occurence.
PNG-24 on the other hand will give you the exact color match.
Also, Save for W&D, JPG quality matters a lot - The same color at Quality 10,20,30,40,50...100 wil give you different color reproductions on the JPG end output.
If you're concerned that much about an offset of +/- 1 hex value to your RGB colorspace, dont save for web & devices. Do a 'Save As' instead. Then use an image editing/ resizing application such as ResizeMe to resize the quality of your document. This, in most cases will retain colorspace information but just drop the resolution and quality of the image - giving you a lesser filesize.

Save for Web & Devices Box Greyed Out

Hey everyone,
I'm trying to save a Photoshop CS4 file for Web & Devices so I can have Photoshop compile the slices and the CSS so I can hand-design rollovers. Unfortunately, all of a sudden the dialogue box for Save For Web & Devices is greyed out... I've check online, changed color profiles, deleted save for web and devices library files, updated Photoshop, nothing. I've even checked past .psds I've designed that I've saved for Web & Devices and haven't changed since--even the Web & Devices box is greyed out for them. Help! What do I do? I need to do this before Friday. Thank you!

Hi
I'm also having the same problem with the Save for Web & Devices Box Greyed Out.
I think it's the plugin that's corrupt, as I've tried deleting preferences and seetings. I can't find the photoshop cd to reinstall it.
Has anyone got the MAC CS4 Photoshop "save for web plugin" (Users/[Username]/Library/Preferences/Adobe/Plugins/Adobe Save for Web CS4/Photoshop/Adobe Save for Web CS4 Prefs) that they could send me.
Thanks very much
Abi

A different take on the "Save For Web" color shift issue...

Ok, everyone who has fussed much with photoshop and "Save For Web" knows about the color shift issue. If you want your colors to look right after you "save for web", you have to work in the sRGB colorspace, and have Proof Colors checked (soft proofing on) and the proof color setup set to Monitor RGB, otherwise what you get looks terrible when displayed in a browser.
But of course if you are editing for print, this is exactly what you DON'T want to do. Well, I work in both. In fact, often the same images, and I want them to appear as close as reasonably possible in both print and web formats, and without a lot of fussing on my part. And I'm pickiest about the print mode, since I have the most control there, so that's the way I want to edit by default.
Nothing new here.
Now comes the interesting part (in my mind, anyway). Obviously there is a known remapping -- because PhotoShop DOES it when you select Proof Colors. So the inverse mapping must also be known (with some gamut issues, but I'm not concerned with those, because, after all, I'm VIEWING it on a monitor anyway!). What I want is a plug-in that automatically applies that inverse mapping so that, when I do a Save For Web, I end up with the colors I've been viewing all the time when setting the shot up in print mode. Then, too, I don't have to worry about what mode I'm in when I'm editing -- it just fixes it when doing a save-for-web.
Again, I want to edit in my normal print mode (typically ProPhoto colorspace, and with soft-proofing off or set to the printer/medium combination I expect to use), then do a single operation (might be a multi-step action) to "screw up" my colors so that when I then do a "Save-For-Web", the resulting image, when viewed on the average color-stupid browser, looks like the image I've been seeing in Photoshop.
Anyone know of such a beast?   I would gladly pay for a plug-in that really works and fixes the problem.
And if you have other solutions, I'm interested, but the absolute requirement is that it I do one single edit pass for my colors for both print and web use, and I get what I see on the screen in PS on both the prints and on the web display (i.e., working in sRGB/Monitor RGB mode all the time won't cut it). And PREFERABLY, let me do all my editing work in the ProPhoto (or at least AdobeRGB) colorspace so I have a gamut closer to what the printer can do.
Anyone got a decent solution for this?

Sorry, I think I'm being unclear. This has nothing to do with individual monitor profiles. In Proof Setup, "Monitor RGB" amounts to turning off ALL color management, and simply letting the monitor do what it will. It is what the vast majority of web browsers do (even if the operating system provides color management, the browsers don't take advantage of it), so that is what you need to consider for images that will be viewed on a web browser. If you convert your image to sRGB, select Monitor RGB in Proof Set up, and turn on Proof Colors, you will see the image as it would appear on a web browser (after you save it as a jpg or use "Save For Web/Devices" to save it as a jpg).   Since almost everyone is running different uncalibrated monitors, there will be lots of variation in how it will look to them, so precise control of the color is unimportant.
That said, I would expect the color on a calibrated monitor (such as the one I use when editing) to be reasonably close to the colors I am seeing while editing in PS. To the extent a monitor deviates from "calibrated", those colors will vary, but a good monitor should show good colors.   Unfortunately, this is NOT the case, as my previous post shows. The colors produced by the steps above are oversaturated and significantly shifted in hue. There is, to my mind, anyway, no reason for this. Adobe clearly knows what the mapping is between the colors as it displays them in PS and the un-controlled "Monitor RGB" -- that is, it is the color map they are using during normal editing display. If they were to reverse-apply that map prior to saving it as a jpg, then the image would appear on a browser on that same (presumably calibrated) monitor very similar to what you set up when editing. Anyone else viewing the image on a web browser with a calibrated monitor would also see good colors. To the extent other viewers' monitors are out of calibration, their colors will suck, but there's nothing you can do about that.
I guess in some sense I AM "asking for a Color-Mamangement-solution for a "non-Color-Management-situation", but specifically I'm asking for PS Color Management to do the best it can for non-Color-Managed situations that we all face every day.
Does that make more sense?

I spent all day Googling and doing side by side comparisons of my old and new systems.
My display is a Dell U2410. It has several presets, including sRGB and Adobe RGB. I've been using sRGB.
On my OLD system, (Win XP, PsCS2, DwCS4) there seems to be no distinction between color managed and non color managed apps, even on this wide gamut display. I could capture (digital camera) in Adobe RGB, open and edit in PsCS2, save as .psd, convert to CMYK for print, or convert to sRGB for SFW. All images looked identical and they printed and displayed perfectly. I thought this was normal, and seemed logical. This also seems to be the source of my incorrect assumptions. I was trying to get my new machine to behave like my old one.
So I get this new machine (Windows 7, PsCS5, DwCS5) and now (still in sRGB display mode) all color managed apps appear de-saturated. Non color managed apps are OK. If I switch the display to Adobe RGB, color managed apps are OK, but non color managed apps are way too saturated. From my investigation, I believe this is normal behavior on a wide gamut display. I've tried changing the Control Panel > Display > Screen Resolution > Advanced settings > Color Management options, but to no avail. Either I'm missing something, or Windows 7 is doing color management differently.
It seems my only option now is to use Adobe RGB display setting for Ps, etc. and switch to sRGB for Dw and non color managed apps. Or, have 2 separate files for print and web. I've Googled 'til my eyes are numb and still not sure I'm getting this. Any enlightenment would be greatly appreciated.
Finally, I don't see an edit function here, so I can't remove my previous incorrect reply. Moderator, please feel free to do so.
Thanks

Save For Web Color incorrect color shifting

SFW (CS3) isn't functioning correctly, or perhaps I'm missing a pref or configuration.
When I go to SFW, the image in the SFW window no matter what setting or level (even 100%) and resulting file is lighter, as in washed out, from it's PSD parent.
Even viewing the Original from within SFW is not the at the original levels. It's washed out.
As a test, if I do a Save As from the same PSD parent to a JPEG at 12, the file is the same level quality as it's PSD parent as expected/desired.
As such, SFW is unusable for me.
CS3, Mac Pro Quade Core 2x3GHz, OSX 10.5.5

Thanks Ann. Here's what I have:
In Edit > Color Settings:
Working Spaces: RGB sRGB IEC...
Color Mgmt Polices: Convert to Working RGB
Convert to Profile:
Source Space Profile: sRGB IEC..
Conversion Options:
Engine: Adobe ACE
Intent: Perceptual
Use Black Point Compensation (√)
Use Dither (√)
In SFW: Convert to sRGB is selected
I'm looking at a head shot 72 dpi and the woman's face is lighter using these settings from within SFW looking at what SFW calls "Original" versus the real original outside of SFW.
Saving a SFW jpg at 100% yields a lighter image than doing a Save As jpg at 12.
I have both a HP LP3065 30" and Apple 22" Cinema display and the SFW processed file is lighter on both screens. Although the SFW Original is lighter on the HP than when looking at same on the Cinema. But the output is lighter and consistent viewing on both displays. Lighter than should be.
The Cinema is set to Apple's stock "Apple Cinema Display" profile and HP doesn't support us with a Mac calibrator, but I did the best I could with Apple's - in Prefs > Display.
Regardless, it seems that SFW is the problem (in my logical but limited color mgmt knowledge). I can save as a Save As jpg and get the expected color level consistent with the original on both my HP and Cinema. Isn't this the deciding factor? The consistency across both. Wouldn't that point to SFW being the problem, since Save As works correctly?
And Peter, I totally agree with you, we need to search first. I did on "Save For Web Color Shifting" but didn't find it. I found other SFW issues, but somehow not my issue. Still, my apologies.
Thanks to both.

Color shift (lightening) when using "Save for Web & Devices..."

Can someone please let me know why I'm getting a color shift (the entire image lightens noticably) when I export an image or animated gif with "Save for Web & Devices...". It happens on PCs and Macs, and with both CS3 and CS2.
I've been using this feature (flawlessly until a few months ago) long enough to realize that there are several settings to adjust the color table, dithering, web snap, etc., but adjusting these settings don't seem to fix the problem. When I use "Save As..." the color shift doesn't occur, and that's been my workaround, but I'm currently trying to save a few animated gifs, which must be saved with "Save for Web & Devices..." in order to retain the animation.
Please help!! Many thanks.

Ah ha! I thought so. The only reason I can speak on this topic at all is because of what I was forced to learn when I started using a Dell LCD flatscreen.
As mentioned earlier, most monitors are pretty close to sRGB, which made web work somewhat easier. However, it seems recently some so-called "wide gamut" monitors have come to market, including the recent crop of Dells. The new Dells can produce a gamut that is closer to Adobe RGB than sRGB. This means -- speaking loosely -- it can produce brighter and more saturated colours than an "sRGB" type monitor.
RGB numbers, in the context of a defined colour space, represent an "actual" real life colour. A very bright red in sRGB colour space may be represented by r255b0g0, but that same "actual" red colour is represented in the wider Adobe RGB colour space by r219b0g0. Adobe RGB, being wider than sRGB, can include still brighter reds than sRGB's brightest red, hence where sRGB hits a roof at r255, Adobe RGB can keep going higher.
Imagine two ladders, each with ten steps on it. The Adobe RGB ladder is taller than the sRGB ladder, even though they both have ten steps. The 9th step is higher (i.e. brighter) on the Adobe RGB ladder than on the sRGB ladder. So if an image contains the RGB values of r219b0g0, well if you assign it to sRGB, it will not be a very bright red. If you assign it to Adobe RGB, it will be a brighter red, because that "ladder step" (like the 9th step) is higher than the same step in sRGB.
This is why your image appears brighter when viewed in SFW and in web browsers. Photoshop knows it's supposed to be using sRGB colour space, but SFW and web browsers DOESN'T, and so it just assigns your monitor colour space, which with these Dell monitors is wider than sRGB.
I think the Dell monitor is fine...I still highly recommend purchasing some type of hardware calibration utitily (one that has a thingy that attaches to the screen to measure the light being emitted). Properly calibrate and profile your monitor, trust what you see in Photoshop, convert to sRGB for web images, and forget the rest. Either way, your images will look "good" on some people's monitors and "bad" on others.
