Well, I know if I choose a box other than the 1st one, it'll hold my color, but that's not the problem. If I want to add 7 or 8 different colors to 20 materials, I have to use different boxes for every one. The problem is that when I start with one color, then modify it, I can't save the modification as a custom color because it overwrites the color I chose it from. So I have to start from a blank box, type in the RGB values of the color I want to start from, then modify it. It's a pitiful system when you think of some of the things computers are capable of. mac
