Lynda Weinman has written several good books about web page designing, all of which you can order from her Web Page. She has a comprehensive discussion of color on her site, Lynda's Homegurrrl Page . We have a copy of her color chart on our site because Jacki uses it constantly while designing graphics. David Chen's discussion of color demonstrates some of the issues about color on the web. The rest of his site is definitely worth looking at too.
