Does anyone have recomendations for learning color theory? I think understanding this topic can really boost any artist's technique, and i havent researched it much at all. So I was wondering if anyone knew a good tutorial or book maybe. Also, on a side note, any of you have an opinion on the Gnomon Workshop DVD's? Im kinda interested in checking some out (for drawing and concept art/digital matte painting) , but thats a lot of money, even if i resell on ebay, and im kinda skeptical on them.
