Kremmen,
Ok, let me correct my words -- please read as "high/low" contrast instead of "good/bad" contrast. High contrast can be lowered with brightness control, but low contract can hardly be enhanced. I'd like to see the lowest-contrast color changed a little darker.
Though I don't feel so much against the high contrast of the current color scheme, I'd cast my vote into the old color scheme. I liked it a lot.
