There is a web-page
http://www.hash.com/users/threechickens/colourtheory which covers basic color theory. It is very basic really, but has some illustrations that might be interesting. If you seach color theory - or something like that - there is a lot on the net on colors.
If you can't/won't load up examples of what you are working with, you could perhaps find some illustrations on the net that cover what you want to discuss and refer to it here.
