personally i don't see the issue as one of colour scheme - it's a usability/readability/legibility problem that's created by things like:
- the bolded sans serif font that's harder to read than a smaller (unbolded) serif font,
- the choice of light grey (font) on dark grey (site background),
- the multiple clashing colours and icons that range across user identifiers, post categories, and user statuses (like resellers and so on) without a coherent and systematic classification schema that makes scanning and selecting content massively more difficult,
- unclear differences in font size between things like the navigation bar, the thread headers, the recent posts window and so on.
there are a lot of other potential problems, and they basically highlight the need for a simpler UI information architecture. the colour usage plays a part in either helping or hindering our ability to easily identify and access the things we're interested in, and colours that help group parts of the site or common functions are a good idea. but the fundamental breakage is structural in the way the site now presents information, at least to me.
unrelated, but trying to type this post was really difficult - not sure what the problem is, but the text field jumps around and resizes, and the text field response to keystrokes is really slow. not having the same problem anywhere else.
hope it helps.
