I use #bada55, I saw it in a comment on HN and thought it was funny. Pretty ugly, but I use HNES on my laptop anyway which negates my topcolor.<p>Also plug for HNES while we're talking about Hacker News aesthetics, it makes HN way better (collapsible comments, inline reply, new stylesheet) and is open source. I've contributed and the repo owner (etcet) is very welcoming.
