Problems with color from Photoshop to InDesign CS2?

Question

Hi all,
Couple of questions:
When I select "Proof Colors" from "View", the color changes a little bit. Is this normal?
Also, on "View", "Proof Setup", which one should I select "Document CMYK" or "Working CMYK" or some other "Custom"
thanks for all your help,
Alex

It's not abnormal, but it will depend on what color spaces the objects are in and the color space that you choose to proof.

You have a lot of choices for how to set up color management. I usually leave my settings set up for my most common situation, US Sheetfed coated and Adobe RGB, but if I have a special job I can reassign the document color space (notice I said Assign, not convert, in order to preserve the native object color numbers). You can proof the color in either the Working CMYK (the one in the color settings) the Document CMYK (if that's different) or something else entirely if you are repurposing an existing document for a new output method.
When you proof colors, InDesign calculates the conversions on the fly and displays the results. RGB objects will almost always show some shifting due to gamut differences, but the type and degree will depend on the rendering intent you specify. CMYK objects tend not to show as much shifting because the gamuts are likely to be closer, but again it will depend on the exact profiles and intents. Objects that are already in the chosen proofing space should not show any shift at all.
There is a caveat here regarding working in one space and outputting in another: If you want the colors to be as close as possible you will be converting to the new profile, which will by necessity change some color numbers to match the appearance. This is not usually a problem with things like photographs, but other things, like type, which is created as 100% K can be converted to a four-color mix which is not good. If you know the output conditions, I always recommend setting the document CMYK to that space when you start.
