take a screenshot (print screen key). Then open ps cs. New document. Paste the image. -Wrong colors-
A little while back I had the same problem and couldn’t understand what happened, but I learned why in the color management forum.
When you press the print screen key, you capture the image in the monitors color space (Monitor RGB) but when you make a new document to paste the screenshot into in Photoshop, Photoshop picks the working space (Adobe RGB, sRGB or whatever your RGB working space is set to inside Photoshops color settings).
When you paste the screenshot into the new document, the colors are wrong because the image isn’t captured in Adobe RGB, sRGB or whatever. It’s captured in Monitor RGB so you have to tell Photoshop that your screenshot is Monitor RGB.
In Photoshop 6 or 7 you can assign Monitor RGB in Image > Mode > Assign Profile and then convert to the the Working Space (or another space if you wish) with Image > Mode > Convert to profile.
In Photoshop CS it’s easier because you can now choose the document color profile before you make the document. Look in the Advanced section in the ‘New’ dialog box.
