Eeegh, these colors are very hard to read. Dark on dark does -not- look good. Blue on black is barely legible, and orange and blue (as both very vibrant hues of their respective colors) create a very sharp contrast on that black/dark background in the forum banner that's actually painful to look at. I'm not kidding when I say I just about go cross-eyed trying to see it.
Change the colors. Please. I recommend making the lettering primarily orange, as that is easy to read on a dark background without being painful. Any supertext or subtext should be either a light grey or light blue. Maybe even a violet color. The banner itself may look much better on a light grey/white semi-transparent background.
This is just...really painful to look at, and not because it's hurting my design senses. I mean it's actually painful to my physical eyes and I can't look at the forums for more than a few minutes without having to look away.
Notice how this particular post is gold. Notice how easy it is to see because it contrasts well with the dark background.
