I have a quite good LCD, but I really have to strain to see so much medium grey on dark grey. I dare not imagine how illegible the thing must be with mobile devices.
Adobe invented colors circa 1986, why not use them ? Get a bit more user-friendliness... and with the right color scheme, we don't even have to look less cool !
Unless all forum users are colour-blind hemeralopic moles ?
At least an optional colourful scheme selectable in the forum options ?
