Change Background color for Specific groups

[laytonw]

I have looked, but cant seem to find the mod for what I want to do. What I would like to do is change the background color of the admin-6, and the supermods-5 and the mods-7 to all the same background color when they make a post. Could you be so kind as to point me to a mod that does that, or explaih where and how to do it, I am usin 3.8 v-bullitin.

Thanks

Layton
