Matching Color of Transparent Rectangle to Solid Rectangle

Hi,
I have a solid color rectangle on a layer.
I would like to create several similar rectangles on different layers with different opacity levels (i.e. 90%/75%/50% etc), that will match the solid color rectangle exactly, when they are against a white background.
I used Hue/Saturation on the transparent rectangles to approximate the solid color, but the eyedropper shows that I am a of couple values off. Is there a way to accurately match these colors exactly?

"...But they don't seem to control RGB values individually-only the direct swatch editor seems to allow direct RGB value entry, and of course, that is useless for a layer with opacity settings, as it only shows the 100% opacity value..."
The above excerpt suggests you are not really grasping the role of opacity. Let me take another shot at explaining it and then I promise not to pound on you further.
Opacity does not change color values in a layer. A pixel with RGB values in a layer of 134/174/154 will still be 134/174/154 no matter what the layer opacity. To appreciate that, underly the layer not with white but with transparency, and check the layer color values as you change its opacity---they will not change.
What you see and the info palette shows, however, is a combination of the layer color value and that of the substrate. The percent of the top layer value contributing to the result is its opacity. The percent of the substrate's color value added is the top layer's transparency, which is nothing more than the inverse of its opacity.
Thus, in normal mode, the resultant color value is a mixture of the layer value and the substrate value, the proportions of which are fixed by the opacity. Again, layer opacity does not change layer color values but, rather, the net effective color value of the layer in combination with whatever lies beneath it. And probably needless to say except that some users think of it as "nothing", the values of a white substrate are 255/255/255---color to the max!

Problem with colorized grayscale TIFF printing as solid color fill

I have a grayscale TIFF that was created in PSD CS5, placed into an AI CS5 file and then colorized with a PMS color. The resulting effect on screen is correct, but when I go to print, it prints a solid (100%) fill of the PMS where the TIFF image should be. I have double and triple checked to make sure the TIFF is grayscale, and I have also played around with various Transparency Flattening settings in AI (both in the file, and in the print window). Nothing seems to work. I even tried a work-around by creating the TIFF as a monotone PMS in PSD, and again it places properly in AI and looks good up until printing when it outputs as a solid 100% PMS. The grayscale TIFF prints correctly from AI if it's NOT colorized, but the minute I add color, it prints as a solid fill. The monotone PMS TIFF never prints correctly from AI. I'm out of good ideas (or any ideas, frankly).
Any ideas as to what I'm doing wrong? Any and all help would be greatly appreciated!

Make sure you are not placing the image into a rectangle, similar to InDesign image placement. The .tiff should be placed as a single element. Then, select just the .tiff and assign a fill to it.

Match color source selection shows up as black

I'm using CS6 / 64-bit. When I try to use the Match Color command (following the very simple concepts shown in tutorials) my source selection color always shows up as black regardless of the actual color I'm seeing. My source is a single-layer simple jpeg (RGB/8) with a rectangle of solid color selected. My destination is a blank white canvas (RGB/8; "Select All"). The preview shows all black and if I say OK to the match the destination becomes all black.

Noel,
I appreciate the thought, and I realize most tutorial examples show something like matching the color of a flower or a piece of clothing, etc., but the concept seems to be simple: take the color from one selection and make another selection be the same color -- never mind size, shape or relevance of one selection to the other. I don't understand why the selection on my source is showing up as black when the selection is definitely not black.

Matching Color

Hi,
Is it possible to match the color of a sepia clip in fcpx if i don't know where the sepia filter for that clip came from as in AE, Motion, etc.? that would be on a 422 mov clip. I ask because i tried using the Match Color option and although it changed the color it wasn't even close to the sepia color i was trying to match. Thanks

There should be a Sepia filter in Effects > Basics.
I have one that offers a little more control.
1) it desaturates the media (so the Amount value goes from B&W to sepiatoned)
2) it adds Brightness and Contrast controls
If you decide to use it, don't save it in the same category as the original!
You can download it here: http://fcpxtemplates.com/fxexchange/Sepia.zip
(if you need help installing: http://fcpxtemplates.com/install4fcpx/)
You can build your own color toner by
1) using the color corrector to remove all saturation (make the media grayscale)
2) overlaying a generator > Solids > Custom and picking a red—red-orange color (or any other color you're "toning")
3) going into the video inspector > Compositing and change the blend mode to (I would use) Color Burn
4) make adjustments to Compositing Opacity and Color Correction > Exposure on the original media clip and probably go back and adjust the "lightness" of the color of the Custom solid.
The Sepia filters are a fixed "grade" of color.
If you need to compare clips side by side, you can select the original in the Event browser and type Command-Control-3 (or go to the Window menu > Show Event Viewer.)

Color Settings: Getting colors in PS CC to match colors of the image when used as a Windows Background

or vice versa. I probably do not know enough to be able to ask the question properly.
The colors of photos in PS CC are not the same when used as a desktop background in Windows 7. The colors are somewhat more saturated when as a background on the desktop and while not totally unusable, it would be nice to have matching color between my PS editing screen and the photo as viewed as a desktop background.
The following are some conditions that may or may not be relevant to the answer of my following question.
1.) I am a complete novice to Color Management so a presumption of knowledge and the heavy use of jargon may not penetrate my head.
2.) I shoot with sRGB embedded in my photos.
3.) My RAW conversions use sRGB IEC61966 - 2.1.
4.) My PS Color Settings are North American General Purpose 2 with sRGB IEC61966 - 2.1 as the working space and Intent as Relative Colormetric
5.) In the Win 7 Control Panel>Color Management>Device, my Device = NEC LCD2690wuxi, ICC Profile = NEC LCD2690wuxi (default), file name = nl269wui.icm
6.) In the Win 7 Control Panel>Color Management>Advanced, Device profile = System Default sRGB IEC61966 - 2.1 and (everything else set to System Defaults too). The only difference from the PS Color Settings being that Windows is defaulted to Perceptual Intent, but a change in either PS or Win 7 has no effect on the relative color differences.
7.) The monitor is set to the Native internal preset, but the relative differences in color remain the same even if the monitor is changed to sRGB, or any other internal preset.
8.) I have Proof Setup set to Monitor RGB but none of the settings will match the Win 7 Background color.
Now, my question is this. How would you set up your color settings/profile in PS and/or Windows to match color between PS and the Windows desktop of Windows 7?

Nevermind. I didn't have Proof Colors checked.

Photoshop uses JavaScript to load open documents into the Match Color command

Hello,
I am a production artist and I make use of the Match Color command quite a lot in my work. I often have 6-10 Photoshop documents open and one of them is designated as my master document. With this document active, I launch the Match Color command. Inside the Match Color dialogue, I load one of the other open documents into the Source drop-down menu under Image Statistics. I click Ok, and save the master document under a new name. I have to repeat this for all other open documents. Needless to say, it gets tedious.
I started to write a script to automate this, but I cannot find the syntax for the Match Color. I have the Adobe Photoshop Cs6 Javascript Scripting Reference but have been unable to locate it in this PDF. I tried looking online, but no luck. Does anyone know what syntax to use as well as associated properties / methods?
Thanks for any assistance.

What we do is we make seamless images from product photos supplied by retailers in the flooring industry (carpet, tiles, etc). The seamless image gets loaded into a virtual room scene powered by Adobe Scene7. Scene7 takes the seamless image and duplicates it horizontally and vertically, in 3D perspective, so the final rendering looks like one continuous product image. Check this link to see an example: http://sitesetup.creatingyourspace.com/wlhhbw4/designcenter/vrddesign.aspx?room=2854 The thumbnails on the left side are seamless images. click on one and it will load into the virtual room.
When I make seamless I may encounter 20-50 images of the same product, but different colors. Rather than spend 10-15 minutes per seamless, I make one and then let Match Color do the rest. Match Color is a great tool for this application. If destructive editing were an issue, the layer could simply made into a smart object, but we're not concerned about that.
I did try the javaScript listener. Below is the code it generated. I'm new to JS so I don't understand all of the syntax.
// =======================================================
var idmatchColor = stringIDToTypeID( "matchColor" );
    var desc7 = new ActionDescriptor();
    var idLght = charIDToTypeID( "Lght" );
    desc7.putInteger( idLght, 100 );
    var idClrR = charIDToTypeID( "ClrR" );
    desc7.putInteger( idClrR, 100 );
    var idFade = charIDToTypeID( "Fade" );
    desc7.putInteger( idFade, 0 );
    var idfsel = charIDToTypeID( "fsel" );
    desc7.putBoolean( idfsel, true );
    var idSrce = charIDToTypeID( "Srce" );
        var ref5 = new ActionReference();
        var idLyr = charIDToTypeID( "Lyr " );
        var idBckg = charIDToTypeID( "Bckg" );
        ref5.putProperty( idLyr, idBckg );
        var idDcmn = charIDToTypeID( "Dcmn" );
        ref5.putName( idDcmn, "4167_13828.jpg" );

How to get the color interpretation ( transparency/opacity)

Hi all,
I am trying to translate colors that may be affected by opacity & transparency into a strong color.
Input colors may be RGB, CMYK and LAB.
Right now, I am :
1) duplicating source color (because Paper/Black can't be tweaked, I need to work on a copy)
2) Setting duplicated color space to CMYK
3) creating a dummy color in CMYK
4) affect CMYK values of the duplicated color by transparency and opacity
ie : source color is Black [0,0,0,100] at 50% opacity and 50% transparent ( frame effects) => [ 0*0.5*0.5 , 0*0.5*0.5 , 0*0.5*0.5 , 100*0.5*0.5 ] = > [0 , 0, 0, 25 ];
5) setting dummy color space to source color space
6) Do my computations based on dummyColor
6) remove duplicated color
7) remove dummy color
The process is working but deltas on teh colors are a serious issue. Not big deltas but enough to corrupt the trust on the color interpretation.
SO question is : Is there any way to get a correct interpretation of a color affected by opacity/transparency settings ?
Do you have any link towars an understandable paper about how lab/rgb and CMYK colors are affected by opacity/transparency ?
Thanks in advance,
best,
Loic

@Loic – nothing much to offer here from my side. Just a source by Adobe which is very likely outdated, but you can look for hints doing research on the theme:
"Transparency in PDF, Adobe Developer Technologies, Technical Note #5407" from 30 May 2000 at:
http://www.planetpdf.com/mainpage.asp?webpageid=837
Especially chapters:
3 Color Compositing Computations
4 Shape and Opacity Computations
5 Groups
6 Soft Masks
7 Color Space and Color Rendering Issues
should get you going. At least a bit. See for yourself…

Hi,
We almost had the same requirement, but we just needed to color a specific column.
Here goes the solution to that, you might do the same for your row highlighting
Changes are required in jsff and one method to be added in backing bean
1. JSFF :
<af:column headerText="Amount"
                 id="c4" width="100"
                 inlineStyle="#{backingBeanScope.BackingBean.cellColor}">2. Backing Bean
//searchResultTableVO is Table's VO
public String getCellColor() {
      FacesContext ctx = FacesContext.getCurrentInstance();
      ExpressionFactory ef = ctx.getApplication().getExpressionFactory();
      ValueExpression ve = ef.createValueExpression(ctx.getELContext(), "#{row}", FacesCtrlHierNodeBinding.class);
      FacesCtrlHierNodeBinding node = (FacesCtrlHierNodeBinding)ve.getValue(ctx.getELContext());
      Row row = node.getRow();
    if(row.equals(searchResultTableVO.getCurrentRow())){
//You can add your inline style for font-style too
      return "background-color:Red;";
         return null;
}Hope this is helpful :)

Trouble Matching Color Between Ps and Dw

I've generated a simple shadow around my page design in
Photoshop (the shadow blends into the background color via a soft
gradient). I've imported a small section of the shadow into
Dreamweaver and placed it in a special table cell to duplicate the
affect in Dw.
This is very simple. I'm using web-safe colors (#336699) both
in Ps and Dw. All artwork was created on my Mac Pro running Leopard
(10.5.2).
When I test my design in Firefox it looks perfect. When I
copy the site folder over to Dw on my Windows XP machine and test
in IE it also looks perfect. It also looks perfect when I open the
design up in Dw on the Windows machine (in the document window).
HOWEVER ... the colors do NOT match in the Dw document window
on my Mac. Nor do they match when I test the page using Safari on
my Mac.
I'm perplexed. I'm somewhat new to Dw, but I've been using Ps
and Gl for a long time. I think I know how to match colors in the
workflow. I recently upgraded my Mac to 10.5.2 and I'm wondering if
this is a bug?
One other thing ... the pull-down menus in the Dw color
selection areas aren't always functional. Sometimes the color
picking windows will close leaving the pull-down menus
unresponsive. You have to hit the escape key to exit. If you are
very careful you can get the menus to work using the middle mouse
button (I'm using a wireless Mighty Mouse).
Can anyone offer me guidance ... or has anyone else
experienced these problems in Dw? TIA.

In Photoshop, are you working in RBG or CMYK mode? RGB output
is the mode
for web graphics. What type of graphic are you using when you
Save to Web
As - gif, jpg or png? Jpg and png will give you better color
matching
control than gif. Gif is capable of producing only 216 web
safe colors (256
minus about 40 colors which are reserved by the various
operating systems or
are not rendered by browsers). Jpg and png can produce 16
million (24 bit)
Truecolor. If you are attempting to color match your web
graphics with hex
#color codes for backgrounds, then your best bet is to use
jpg or png.

Indexed color and transparency in PNGs

I'm working with a software developer who is revising his subtitle rendering application to meet my company's specifications. The renderer produces an image sequence, and we agreed on using PNGs with a transparent background as the format for the image sequence. The renderer is producing PNGs in Indexed Color mode, so Photoshop and Windows Photo Viewer recognize the transparent background, but Premiere Pro CS5.5 and CS6 don't. I can re-save one of the PNGs after switching it to RGB mode in Photoshop, and then Premiere Pro recognizes the transparency. I'm not surprised by any of that. What I am surprised by is that the software developer says he can import the same PNGs, without switching to RGB mode, into his copy of Premiere Pro CS3, and Premiere recognizes the transparency.
Is there anything I can do besides batch processing in Photoshop to get Premiere Pro CS5.5 or 6 to recognize the transparency in an Indexed Color PNG? Has something changed since CS3? I did look under Modify>Interpret Footage to make sure that my Ignore Alpha Channel box is unchecked for the PNGs, but I can't find another relevant setting to check, and I can't figure out why CS3 would be able to recognize an Indexed Color PNG.

PNG's need to be RGB.
CS3 was a long time ago..
You can however import gif in indexed color with transparancy.

Change a color to transparent.

Lets say i have a black pen inked drawing of some complex object, drawn on a white background.
If i want to change the white to transparent, currently the only way i know is to export it to gif and changeing the white color to transparent in the process.
After the export, i can import the result and i now have what i wanted.
There are a few problems tho.
1) what if there are more than 256 colors?
2) what if the image was scanned and there is a tolerance to the white that i want to convert?
I cannot use any of the marquee tools as the object is to complex.
There must be a way to do what i want.
I am at the beginnings of my fireworks learning curve, but i cannot for the life of me figure out how to do this.
Thank You
Jerry

Hi JerryCied
As far as i know there isn't an easy way to achive this.
When your object is too complex, you have to make it through, mostly by hand.
- Use the marque tools and the properties panel to make changes to the edge style.
Use either anti-alias or feather for a smoother result.
- Use the polygon and lasso tools to be more accurate when you cut your object.
- Take the risk and use the eraser tool to delete every single pixel that you don't need.
- Make changes through the filters panel to your object, so it reaches the look that you wish.
Take a look at the 'R' tools (blur, dodge etc). Maybe you can use them too.
For example you could use blur tool to make a smoother edge.
thanks

Gradients foreground color to transparent

CS4, using gradient tool on toolbar
Obviously, I'm not understanding something, or I'm doing something wrong. What is it?
Here's what I did:
Create one layer and fill it with black.
Create a second layer above black layer and select it. Open gradient tool.
The gradient tool has the 4 blocks, two at each end. I use the lower left block to set the color to blue, and I leave the block above it to 100% opacity.
I use the lower right hand block and set the color to white. I set the opacity to 0 in the upper right hand block.
I draw the gradient on the new layer. I'm execting to see a blue gradient that fades to black, but rather it fade to white.
Why is this?
More importantly, what do I have to do to get the gradient to fade from blue to 100% transparency to reveal the color of the lower layer (black in this case).
TIA.

I now have the pixel transparent gradient working. Utlimately, it was user error, though
I think the design leaves a bit to be desired.
The problem was, I had not notice the checkbox for "Transparency" on the gradient's option panel. It was not checked. As soon as I checked it, I was able to drop transparent gradients on the transparent layer and they worked as expected. Personally, I would think if one designed a gradient with 0% opacity at one end, that should be enough to have a foreground color to transparent gradient. Don't know why there's the second step.
But, all is good.
Thanks for your assistance.

Error -1074395395 occurred at IMAQ Match Color Pattern after merge programs

Dear all
I have 2 separate programs that use same source image (red01a1.jpg). The first find location of color particles (color location 01.vi) and second find location of particles after threshold color image (particle location 01.vi). Both of them run good.
But when 2 programs were merged into one program (color sorter 01i.vi), that happened error . The error message is “Error -1074395395 occurred at IMAQ Match Color Pattern”. How can I fix it ?

IWeb 09 - Color picker not selecting matching color

I have tried to use the color picker to match colors in iWeb 09 and it seems impossible to match the colors. I go to the color picker and use the magnifying glass to try to match an existing color and the selected color is not exactly the same as the color I am trying to match. Very frustrating. I have searched and other folks have been reporting similar problems.

When are you seeing the mismatch? In iWeb after applying the magnifying glass or after publishing? What are you trying to match? Backgounds? Objects? Text?
It's been noted that after publication some colors have been changed in the css file from the rgb alpha code it was originally set to to the # number code (or vise versa - I don't remember which) which changes the published color slightly. Tried to find the topic just now but couldn't.
Definitely a bug to be reported to http://www.apple.com/feedback/iweb.html.
If you're trying to match a page background to a browser background and you're not using a theme that uses images for it's background you can set the page background to none and let the browser background color work for both areas.

Histograms in Match Color

Hello,
As we all know, the Match Color utility was a great addition to the Photoshop series. But it does lack an important feature. When I have two images, [1] and [2], and I choose one image [1] to match color to, it copies colors that I see to the [2] image, but it does not preserve the brighness of the [2] image. In very most cases I want to preserve the brightness, so:
the Match Color screen should look like this: on the right half, the [1] image (or layer) preview, and under it, the histogram. On the left half, the [2] image (or layer) preview and its histogram. There should be the selection tool at the [1] source image screen half. Corresponding to what parts of the source image I choose, the histogram value should change, until the histogram of the selection will look like the histogram of the [2] image. Then I press the OK button and for the final image I get one with colors matched and brightness preserved.
Very useful for ones using the Match Color option intensely.
Thank you.

Folio Preview is only for Digital Publishing Suite output and isn't the best way to preview. The most accurate color can be see if you choose View > Overprint Preview. You DON'T want to disable color management, in fact, I don't think you really can.
