GB setting I've missed somewhere?

I'm hoping there's a setting I've missed somewhere, but I'd like to change the "theme" of the site, if possible.  Not my background - that won't do much. 
 
Basically, I'd like to make the site more Windows-default-colored than this darkness so that I don't have to alt+tab as much at work :P 
 
Did I miss where to do this, or is this simply not an option?

You can swap between a light colour scheme and the default dark colour scheme using the icons in the bottom right of the drop-down menu that appears when you click your username in the top right of the page.

Aha!  Thank you, that's much better :)

Hmm the comments about it for Chrome don't seem too thrilled, but I'll check it out, thanks again :)

Blasphemy. Black on white is like staring into a lightbulb. "

I can't stand the white site; it murders my eyes.

I'm not particularly a big fan of it, but I can rest a little more easily when people walk by that might eye my monitor.
