Right now, the utility I'm writing for Debra will change all diffuse (Kd) colors, all ambient (Ka) colors, or all specular (Ks) colors in a PZ3, PP2, PZ2, or CR2 to a specified value. Tonight I will enhance it so that, as an option, it will only change those colors that are black. This will keep it from messing up any highlight colors you have for hair, and such. I'm trying to keep the interface simple (the default will be to change all black highlights to white), but if y'all can think of other color-related functions that would be useful, now's the time to speak up, while I have the code open.
