I don't know if I'm the only one here who works by saturating grayscale with colors, but if there's anyone else here who does, you may be able to help me out. My problem is after I've colored a piece, I want to make the lighting look a bit tinted. You all probably know that when you saturate grayscale, your light source always looks white. I was wondering if there was a way to tint the lighter areas to make them appear like a colored surface undernieth a differently colored light source.

any help would be appreciated.
