Having a variety of colors to distinguish the characters makes sense, but the show has enough character development to make me believe that Razer won't stay red forever. Who knows, maybe we're both right and he'll stay red for the duration of the show and go green in the last moments of the final episode. The idea of learning to channel anger is a good one. I'll have to think about that some more. I've always seen anger as a negative emotion to be gotten rid of, but real peace/power/personal growth etc is said to come from acceptance and integration, so you may be onto something with regards to the Razer's development. Or his journey may lead to a transition to another color. Back to square one.
