Here's my issue:
I have a guy wearing a bright green shirt in a scene. I can change the color of the shirt to a variety of colors except black. White doesn't work either. I've tried a bunch of different things and looked all over for an answer, but I'm coming up short. Anyone have a suggestion? Thank you!
I'm using CS 5.5 on a Mac, btw.
Well, without seeing a frame nobody can advise. Suffice it to say that Change to Color is probably the most wrong effect for what you have in mind and your overall approach may just be wrong... Y'know, there's Hue/Saturation, Tint, Tritone and a gigazillion otehr effects and techniques I can think of, but naturally, they will require some masking and otehr procedures...
What Mylenium said,
I would think the best solution would be to mask out the shirt, then use tint, Black and White, or one fo the Hue/Saturation/curves etc type effect. If I am not mistaken (and I very well might be) I dont think that Black and White are seen as "Colours" as such - that is probably why it is not a choice.
