It's been about a year and a half since the Modern theme became available, which brought with it new colors for Fanfare, IRL, and Jobs, which were and are white in Classic. There were a few requests for getting the colors added to Classic, but it never happened. Maybe now is the time? [more inside]
Could Recent Activity and Favourites be somehow colour-coded? [more inside]
Can the anchors in the "posted by" line have a different link/visited color than anchors people put into either the post or their comments?
QuickTwoPonyRequest:  Can a background color for alternating comment s be used to aid readability?  Can tags, category and poster information be added to the two RSS feeds?
COLOR THEORY CRYBABYFILTER: I love the blue and grey of metafilter, but find the green of AskMefi to overwhelm me, and in kind of a swampy pea green soup way where I can feel ill if I read it too long. Is it possible to offer another background color, similar to the white screen you can get in your preferences when the Metafilter blue gets similarly distracting? I love AskMefi but that green really gets overwhelming at points.
I think Metafilter is the best thing there is. When I saw the bright ,colorful,sparkling "Spooky Filter" on the home page, I realized what I have been longing for more than anything in the world: being able to choose a brighter color pattern for my personalized viewing pleasure. Am I a heretic ? Will I mercilessly burn at the stake?
Matt, in the customize section, could you also make it so that one can customize the link colours? I'd really like to change the links from yellow to say orange. Not sure how hard it would be, but it would be a nice addition. Thanks...
