Yes, it is, but I agree with Mario (and I already wrote this in another thread) - The high contrast between the text and the background makes the forum hard to read, at least if one reads a lot.
I, too, would like a color scheme with a bit less contrast. On the plus side, this forum has a bit bigger text than many other forums, that is good already for the mole type people like me. (Mole = semi blind).
