I don't know what age level you're looking for, but this is a Color Theory site that would be applicable for H.S. students. I actually used it in a college Color Theory class.
It's pretty neat and the interactive parts are cool.

I now have a computer for my students but I don't have any art software for
my them. I am looking for some cool interactive websites for my students to
go to when they finish their work.
Thanks for all you do!
