Make this a premium advantage:
- Save your eyes: Get a normal forum colors scheme that does not kill your eyes.
There's a plugin to Chrome called Change colors. It works
Actually, between the current scheme and its negative I'd take the former any day. I'm one of those guys whose terminals are white on black, since I find it less aggressive to the eyes. Don't change it :P
My guess is - make colors configurable per user. It shouldn't be too hard.
