Feature Request: change colors on individual chat channels

[nevlik]

I can't read the Cutscene Captions channel text due to the purple/black color scheme. I'd like some way to change the color. Text file changes would be fine.

Hey while we're talking about chat colors, how about customizing our global handle color, or even just getting a reroll on it? Mine is hideously ugly and I'd love to be able to either set a new RGB for it or play the lottery once a week or something.
