Colored thread titles

[Smashbox]

I've seen a few Xenforo sites have colored thread titles. I was wondering if they are doing this by just entering some css into the title or is there an add-on they are using. If it is an addon could someone point me in it's direction please? It would be really useful to differentiate between regular and sticky threads.

Thanks!

Sticky threads have their own CSS class: http://xenforo.com/community/threads/apply-css-styling-to-sticky-threads.8967/
