6/10
Well, it's different shades of mostly the same color, which is good. (+1)
The black font is hard to see (-1)
The darker font on the footers are not that easy to see either (-1)
The border on the controls irks me a bit (-1)
The background seems a bit to light to fit in with the rest (-1)
The tab font colors aren't that nice either. (-1)
I'd try sticking with either a main light or dark theme, but try to incorporate lighter font colors in them, don't use dark color fonts with dark bg's (Same goes with light) but at the same time don't use bright colors, but your profile has good potential! :D
