Reason why the majority have kept the default is because our gallery uploads need to look good on the background and changing that just defeats the purpose. Since visitors will see the default, we need to see it to and plan for it. Doesn't mean we like it. Personally, I like the forum white, but not sure about the gallery white. Maybe its ok, many galleries are white. I thought black drew out the colors better. I do truly lothe the brown though. Its like soooooooo uninspirational. Put a yellow / gold gradient with some maroon and teal or whatever, but spice it up a bit and get me going so I feel like rendering instead of feeling like its time to go .... ok, I'll stop now.
