Have a little cookie with that milk, have a little pancake with that syrup, have a little…waht? Tan with that grayscale?

I’m having problems with Photoshop CS’s color settings, or maybe my monitor’s color profile; either way, my grays in Grayscale mode are tinted with an ugly tan. Compare these two images, the first, desaturated RGB:

The second, changed into Grayscale (!):
www.legographics.net/bad.gif

Now, tell me that that second one doesn’t look tan to you. The Info pallete doesn’t even say it’s gray after you do a print-screen-paste of the "grayscale" mode.

I’m using my monitor’s color profile, Gateway FPD1530, with Gray set to sGray and Spot set to the default Dot Gain 20%. Changing any of the modes does nothing but change it to a different shade of gray, none making it true gray. Also remember that this discoloration only happens in Grayscale mode, strangely enough.

I note as well that such a problem did not occur in Photoshop 7.

Have a little question with that answer.

I too am having the same problem. However, I have two monitors on my system. One is a Gateway FPD1930 and the other is a Sony SDM-P82/B. I’ve found that on the Gateway monitor all shades of gray appear as a tanish yellow thing. And as you I have noted that there is not a problem in PS 7 or PS 6. Perhaps it’s our monitor profile or something of that sort. I’ll let you know when I find something.

Yes, first is grey, second tan. It sounds like a colour mgt issue. What is your working space and file space? I don’t think it is a monitor profile issue, because I see the same thing you do on a calibrated monitor.

Ok, I think I’ve found it out. It’s a Gateway Monitor problem. I’ve composed a PDF document with instructions on how to fix it and hopefully my English won’t be too hard to understand. I’ve posted it at ( http://www.matthewkimber.com/PhotoshopCS_GatewayMonitorProb. pdf). Hope this helps!

That didn’t seem to fix it, unless I’m missing something here…

By the way, I don’t have 2 monitors, and I have a GeForce4 MX 440 128mb, so the problem might be something else (but I hope not)

Try remaking a monitor profile.

The two monitors shouldn’t have anything to do with my particular problem. The only reason I mentioned that I have two monitors is because on the Sony everything looked fine and on the Gateway monitor the gray was a tan color.

Perhaps your problem isn’t the same as mine. When you open up Photoshop CS and double-click the color swatch to open the palette do your grays look like varying degrees of tan? If so, your problem is most likely the monitor’s color management profile. Obviously Adobe has changed the way that they do color management to rely on the individual monitor’s color management profile. Try changing it to various profiles. You will probably need to close and re-open Photoshop and perhaps even reboot your machine.

By the way, what operating system are you running on? I am on WinXP, so that may be another difference in our problem. Let me know how things are going or what your final resolution is.

Andrew: Matthew’s problem is unlikely to be the same as yours. Yours is a colour management issue outside your own monitor profile, not a monitor issue. Yes, the first is grey. Yes the second is tan. Not just on your monitor. So the problem relates to your file’s assigned colour mode and any conversions that might have been done. So again: what is your workspace and what is the icc of the file?

I saved the tan image and opened it in CS only to find that it’s in 256 color mode, not greyscale. I converted it, saved it, and it’s fine and dandy. I think you have a setting skewed or possibly missed a step when you saved it.

Tempus: I think the gif was made just to show the colour shift, and thus saved as 256 colours. If the demo was supposed to be greyscale, you are right.

The later is correct, I did a print-screen>paste>crop, But it does end up as the same tan color if I convert it (the good image) to grayscale and then back to RGB. Notice the blue line at the bottom where I missed cutting off the window 😉

Well, let me tell you this; when I first started CS, it told me the monitor’s profile was corrupted; however Photoshop 7 told me this as well, the first time it was started up, and ignoring the warning still worked.

There is a thread on colour mgt: print-screen will copy file with monitor’s icc. If the original was AdobeRGB or sRGB, the print-screen>past>crop will cause false assigning of profile. (look at "Red Changes to Orange in Photoshop")
