Custom thread background colours (like stickies)

[mantisinc]

Hi guys,
I was just wondering if there is a hack out, or any way to do this.
Basically what I would like, is to be able to change the background colour of a thread when it has been posted, so it stands out over the others.
I only want to change the colour of the background of the thread in the forumdisplay, for example, like how the background colour of a stick thread is different.
I don't want the background of the actual post to change, just the cell in forumdisplay where the title of the thread is displayed in a forum category.
Any help is much appreciated =)
Thanks in advance!
