background color of just the currently active users area

[boandmichele]

i have searched through all kinds of stuff on in the forumhome template, and i cannot figure out how to change the color of the currently active users area. i know that it is alt1, but i'm still not sure what to change.

i am adding a dark style on our site, and putting it together myself from a duplicate default theme. we have the html markup mod for our users, and when you put together different username colors with a dark background, you get unreadable text.

any ideas? i figure maybe this is something that can be done in the stylesheet, but i'm clueless as to what to do.
