I just thought that this information might be useful to some of us that use colored text in our posts/signatures.
Fluid Dark! Because the white burns and I like posts to fit on my page :3 Although the banner doesn't look as good in fluid skin...
Yeah, on the fixed width skins the banner is just a regular image, which gives us a bit of freedom with it. On the fluid skins, however, the banner too must be 'fluid'--so it's actually two images: a repeating pattern that looks like the background, and the transparent overlay logo. This unfortunately means we can't have the same light effect on the fluid banner that the fixed has. :'c I'm using Fixed Dark, at any rate. I switch between Lite and Dark, I really have no preference. My screen is tiny so fluid or fixed doesn't really make a difference to me--they look identical, aside from the banners.
