Different Threadcolors

[acabmg]

Hey folks!

Currently i am confused.. :D Is there a way to change the bg-color from different threads on the threadbit?

example:

Thread 1) background-color: #bbb
Thread 2) background-color: #aaa
Thread 3) background-color: #bbb
Thread 4) background-color: #aaa
Thread 5) background-color: #bbb
(...)

I can't find any css-declaration :(

sorry for my bad english and greets from germany!
