Assuming fox and HG are cool with it, I'd love to ticker around with the colors to get it all fancy and updated.
I fully support this. Careful while you do, though, because you're tinkering with the board's code and I found last year that there was some (minor) potential to bring the whole fucker down.
I'd also do the thing that I sadly did NOT do, which would be to make note of the current settings and maybe PM them to yourself in case something goes south and we need to temporarily switch it back while further adjustments are made.
All in all I think the dirt color of this year's festival artwork will be much more pleasing than the sky blue thing.
There are a shit-ton of tiny little tweaks you're going to have to make; all of the headers, text, hyperlinks, etc. have to be adjusted individually so I advise waiting until you have a good two hours to fiddle with it. Brown shoes with a blue suit is tres gauche.
