No, not with yellower tones! :P
With the paler colours on _testindex the background is perfect for the others, don't change it! :P

I'd like it if the wiki comments boxes were one of the bluer colours, rather than grey, but I'm not too fussed about that :P

I think the pale background is good. It's a shock after having darker colours, and looks a little baleful at first, but people'll get used to it >.>
