Color accuracy in Keynote?

What's up with colors in Keynote? I use the color picker to create a very rich orange, then when I apply it to an object on a slide, it comes out as a washed-out almost-yellow.
Anybody else having problems like this?

Okay, I found my problem (though the Keynote UI is very confusing in this regard.) If you click on the object, open the Colors Palette, set a color, then drag it onto the object, the object changes color...but not to the color you want! If, however, you click on the object, click on the "Fill" button on the Format bar, open the Colors Palette through the Fill pop-up (not via the toolbar), it will all work as desired.
Very weird.

Correct Color Profile in Keynote '09 (or '08)

I have been tasked with putting together a photography presentation for six photographers. The presentation will be projected (with two Epson projectors and six color monitors) in Keynote ’09 (and ’08) for a one-night photographer’s gallery exhibit. One of the concerns raised by one of the photographers who has used Keynote (not sure the version, but probably ’08 or earlier) is that there is a "*color shift*" that occurs from the original saved image. All images are exported from (Apple) Aperture, (Adobe) Lightroom, and (Adobe) PhotoShop CS3-CS5 using the Adobe RGB 1998 Color Profile.
All photographers (including myself) are working with Aperture, Lightroom, or PhotoShop and are saving their final images with the Adobe RGB (1998) ICC color profile.
Is there a way to ensure “correct” color profiles are used in Keynote ’09 (and ’08)? If so, how is this done?
Any help would be appreciated.

Welcome to the discussions, anthonysan.
There isn't a way within the program to do it, however it IS possible I think. I'll give you some tips to start down that path, and, if you have any questions, just post back here.
First, go to Keynote preferences and, under General Preferences, choose "Save new documents as packages". Next, create a new document (white theme), change the Master to blank, and place three rectangles on the first slide, each with an EASY to define color. (By "easy to define" I mean pick colors that you would be able to discern numerically, for example 100% red, 100% black, 100% green, etc.) Finally, double click inside each shape and add some unique text. I'm using "firstone", "secondone", "thirdone".
Now, save that document, then right-click (two-finger-click, control-click) on it's icon in the Finder. You should see an option to Show Package Contents. Select that and you should then see a few folders and some files. You're looking for index.apxl.zip. Double click that one to unzip it, then put the .zipped version in the trash (Keynote can read either just as well). Now, you should have an index.apxl file.
When you double-click the index.apxl file, you'll have to choose to open it with TextEdit, then search for your unique text "firstone".
Things get more detailed from this point, but it does lead to a potential solution. Let me know if you're following so far, and we can look at the mysteries within they Keynote file

How do I add a color pallet for Keynote and Pages?

This seems like it should be straightforward, but I need to add a new color pallet for use with Keynote and Pages. I have the .clr file, but I'm not having any success getting it to show up in the color picker.

Within Keynote, show the colour palette (command shift C or view > show colours)
click the image palette button (arrowed)
click the Palette drop down menu and select either: new from file or new from clipboard

Color Management in Keynote

Hi, I'm pasting a .png logo in Keynote. The color is just different. Can't find any place where I can manage the color adjustment for keynote. Need solution for this issue. Can someone help me please?

There is a colour adjustment control    View > Adjust Image
As to colour management you would need to supply more infermation:
where did the image come from, your own camers, a web page?
what colour profile does the image have:    open the image in preview and open the inspector:
command I > colour sync profile
what colour display profile are you using:   System Preferences > Display > Colour

How to rival the color accuracy of "Camera Standard"

Can anyone point me in the right direction: Do you know what tools or even spectral instruments I would need in order to create a DNG profile with similar color accuracy to Camera Standard? Twisted profiles created with color checker charts don't seem to behave equally well, which makes me wonder where the difference lies, and what tools would I need to be able to create or even tweak profiles with accuracy & wide-spread applicability?

Yes and no... Adobe has profiles for the camera, but I find the need to diverge from them.
The biggest part in my mind is knowing where to begin to rival the color accuracy of "Camera Standard," or "Adobe Standard." I feel like this is the "unknown" and I'd like to build a profile from the bottom up in a way that I could improve on these profiles or at least rival them, without inadvertently degrading them.
Is there anyone like MadManChan2000 that could simply point me where I need to start or where I need to do my reading?
Thanks so much,
Bert

.jpg import color accuracy

I need to preserve exact color accuracy when I import a simple line graphic. If I import a perfect .jpg or perfect .gif file image, with lines of perfect cyan in the image, when the image is displayed, the lines have been "smoothed out" at the edges by adding some portion of black to the pixels. In the Media file that iMovie creates to store stills, clips and audio, the original graphic image file can be found (graphic.jpg) along with an additional, corrupted file (graphic-1.jpg) which is the image that iMovie apparently uses and has been modified as I described. How can I prevent this?
Thanks very much!

we stumble into a bunch of unsolvable problems:
a) color precision - an issues since the beginning of picture processing with computers... what ar we talking about, RGB or CMYK? in case of RGB, we have it a ittle easy, because that's how Monitor work... you need to calibrate your monitor AND you need to set up the color profiles in your grapgic apps...
b) .jpg - is not a color precise compressor, you should choose any lossless codecs as tiff (huge files, but... quality has its price)....
c) changing compressor codecs - you have to switch the codecs, because "dv" has a totally different color scheme then anything else... (and iM works with dv....); dv is a mainly a video-format, pointed to work with tapes and and TVsets...; the dv codec just store every 8th pixel some color-info.... color precision on TV...?? lol
d) video standards - why do we Europeans make cheap jokes about NTSC (=never the same color)....? because it's true...
e) resolution - you create your graphics on a hiRes computer screen without interlacing... dv uses about a quarter of res, adds interlacing, less colors....
f) iMovie/any video! can just "estimate" the colors of your grafix....
solution: judge the final pic quality on a TV; choose "TV safe colors" (e.g. red=NoGo, neutral grey=NoGo, any "plain,pure color" (as cyan) =NoGo... now you know, why 90% of sets in TV sitcoms have greenish walls... green=good with NTSC...); choose non-serif typo; use BIG grafix....

Global color replace in Keynote '09

I use my own palette for my keynote presentations, using each color for a specific purpose consistently throughout. But I usually want to fine-tune these colors when I ultimately connect to the projector I'm going to present on, to compensate for both the projector's color capabilities and the room lighting. Is there a way to do this quickly, to change a color in a palette globally across the entire presentation? Or do I have to define a new color and change each diagram individually? What do you experienced keynote folks do to solve this problem? I'm a bit of a keynote newbie...

Identifying colors in Color palette in Keynote

Hi! I'm new to Keynote and trying to figure out how to identify the color number/values (RGB, CMYK, hex number, ANYTHING!) of a color in the Colors palette. I'm also wondering whether there's a way to type in the color values of the specific color I want vs. just using the slider to approximate it.
Is this possible?
Thanks very much for your help!
Margaret

Thanks so much! I have no idea why I'm not seeing those things, but I'll try to figure out what's wrong with my system.
Much appreciated!
Margaret
Margaret, if you select the colour sliders, the
palette should show you the numeric values that the
sliders have, and let you directly change those
values. Furthermore, you can select what colour
model the sliders use (gray scale, RGB, CMYK, HSB).
If you aren't seeing the values in the sliders
palette, then something is likely wrong with your
system.
(By the way, here's a colour palette tip that many
folks might not know -- you can add any colour on
your screen to your palette by using the small
magnifying glass in the colour palette -- click on it
once, and it will change your cursor into a
magnifying glass; click again, and the colour in its
crosshair becomes the palette's selected colour.
If you like this, but want more control, or hex
values for RGB, the DigitalColor Meter application,
in the Utilities folder in Applications, will allow
you to determine the average colour of a spot of a
specified size.)

The ICC uses LAB D50, as does Photoshop.
Marco,
>>>
(prof. Boscarol) on his forum:
>>>
1.Lab is not absolute and there are infinite Lab.
>>>
2.The illuminant E is a theoretic reference illuminant
I must disagree with the implied conclusions in both statements, but with a friendly, not confrontational tone. And, Adobe and other software may be assuming Lab is D50. I cannot and would not dispute that.
What I said is that if you follow CIE math, the color values in Lab mode will be at Illuminant E. I stand by that conclusion. But there is little in the way of enforcement when it comes to standards.
Lets start with the CIE color values from measurement to numbers. This is the illuminant times the subject (measured) times the standard observer. It requires matrix arithmetic because the operations have to span the visible spectrum. So it is a little more involved that simple multiplication, but that is not conceptually important at this point.
The light source may be defined by a standard such as D50 or D65 or it can be provided in a custom set of tables (from measurements). The subject (raw image) values are adjusted for the measurement instrument to represent illuminant E (equal energy). This would be the spectral response of the color filters and such in an image sensor. The standard observer values are provided by the CIE, again at illuminant E. The resulting XYZ values are at the white point of the illuminant used for the source light.
Before moving on, the image sensor spectral response tables are too often not available. Thus assumptions are made that make calibration so bloody difficult. Enough said.
These XYZ values are then transformed to Lab values. The math in this step effectively removes the original light source from the XYZ values, resulting in illuminant E. This is how it is described in the literature, Berns, Hunt, and Wyszecki. If one adheres to the rules, Lab will always be illuminant E. XYZ values without a white point definition are as meaningless as RGB values without a profile definition.
But there is no enforcement body. I have seen lots of code that does not adjust for the XYZ white point at all. In that case, there would be an infinite set of possible Lab white points.
If you assume Lab is always D50, D65, or whatever floats your boat the transforms from RGB to Lab to RGB again would not be compromised. The ICC does define a white point in each ICC RGB profile. So if the input colors are correct, the output colors will be correct. It isnt too important what white point is used for the intermediate step.
But if you take a file in Lab mode from some other source, the white point would be very important. If I give a Lab file to Fred in E and Fred assumes it is D65, color conversions will be wrong. If Fred creates one at D65 and hands it to Adobe, chaos reigns. The ICC does not have a profile for Lab mode that I am aware of. So I dont know that the ICC attempts to trump the CIE as suggested. If someone knows of a verifiable reference for this, I would love to hear of it. The TIFF metadata does have a tag for white point. But I have never seen it used in a Lab mode file, including Adobes.
Illuminant E is no more or less theoretical than any other Standard Light Source. But it is at the core of all color matching algorithms and the basis of the standard observer target values. It is most often simply referred to as the equal energy light source so it might not ring a bell like D50 or D65.
The conversions between Lab and LCh and the algorithms for Delta E 2000 color differences are all implicitly dependent on Lab values at illuminant E.
I rest my case.
Cheers, Rags :-)

Can i change color mode in keynote?

Whenever I import pictures or logos to keynote, the colors turn out really skewed as from how they should look like.
COuld someone please tell me what might be wrong and how I can fix that? I have tried several differnt options when I export files from illustrator. Strange thing is, they llok perfect in Finder and Preview.
Panicing here. Thanks.

I have just had the same issue. I am importing a logo I have created in Illustrator, which was done in RGB with specific values. The following methods all produced result that was different than the source…
-Copy/paste the logo from Illustrator with sRGB profile active in the document, and with no profile, with the same result.
-Placing the EPS directly was different again.
-Placing an AI file with embedded sRGB profile. No good either.
I also usually generate a PNG for client to use and when placing this into Keynote the colours were correct. The PNG was created in Illustrator with sRBG profile active. This worked for me, but I have seen other say it does not.
I've seen someone else claim changing the colour profile in Photoshop etc to the same one used by your screen will fix the shift, as Keynote supposedly uses the profile you have in system prefs. I tried this and it made no difference.
I assume the issue is colour profile conversion, but see no method that fixes it. Other than PNG.

Color Window in Keynote Problems

I am working in Keynote and find I cannot get back to the full Color Wheel. Under Palette all I have a choice of is Web safe colors, Developer, Crayons and Apple Colors. Very limiting. Color wheel is not available. I must have turned something off, but can't determine what it is. Any suggestions?

Msi GTX 760, Multi-Screen, HDMI Color accuracy way better then DVI

Hi,
I'm using two HP Pavillion 23xi screen.
At first, I decide to connect one screen using the HDMI output of the video card, and the other one using DVI. There was an astonishing difference between the two.
Ok, maybe the screen is the problem. So, I switch the connection between the two screen. Same result. HDMI look so better. For exemple, if i open paint between the two window, the hdmi connection show the empty white canvas like it suppose too, but the dvi screen is showing the canvas almost like a light grey.
Maybe it's the default behavior, but i'm sure something is wrong.
Is there a settings somewhere that i'm missing to make both output port behave the same way.
Best Regards,
Patrick.

if there is a setting it will be in the Nvidia control panel (probably under color for the output and you may need to adjust the color response curve)

How do I keep the original background color in a Keynote presentation after PDF?

My Keynote presentations have a grey background. But when I convert to PDF, it turns to black. Help?

Hi jvtennis,
What are you using to convert your file to PDF? Are you using Acrobat or "printing" to PDF from Keynote?
Regardless, one thing to check is that you have Show Large Images selected in the Page Display settings in Acrobat or Reader.
Best,
Sara

Default Chart Color Set in Keynote '08

Hi!
I have several charts on successive slides. I'd like to keep the colors used for some data consistent across all charts in which they appear. I can't seem to locate the default color samples and I'm pretty sure I've been through all the 3D and 2D samples.
How do I find the default colors used in bar charts?
Thanks!

Instead of going to the graphic section, go to the Chart Section (8th from the left) and then in the top right hand side click Chart Colors. From the box that pops up, select the color and drag over the section of the graph you want that color.
