I am planning to switch back to grayscale, but that'll take me more time than I have at the moment - give me four hours or so (including my commute home from work). I hated that the individual comments weren't outlined (which sometimes made it confusing: which "reply" means "reply to comment" and which one means "reply to the entry as a whole"? It's not clear unless the comment, including its "reply" button, is in its own little handy capsule) and small caps were forced, which was the main reason to switch from default. But yes, grayscale returning soon!

Edit: does at least making the main text black and white help? Not sure if I'll also change the purples to shades of gray, but that should help a lot.
