Red header looks bolder. Duller, but it jumps off the page more. Oh, and the little white line at the top is gone.
Actually doesn't look good as my browser toolbars are sky blue, but if I F11 into fullscreen it looks good. (But I don't like red to start with, so take that with a grain of salt.)
Hey, you know what would be great? If the website had a way of detecting what PA Platform theme you're using, and themed the site after it. Or maybe if you choose a "Favorite PA Platform Theme" in the user profile, and it takes it from that. So the site matches the Platform. If the theme is Dark, you could also invert the colors (i.e. white text on a black background).
Just a thought. I know the site isn't first priority, the platform is, but a guy can dream, no?
