Custom code or css to modify this mod?

[Sharingan_Okami]

I will try to make this as detailed as possible.

I have a mod that shows fake users online.
(i know its low and people think very badly of it, it just makes the forum look better since its new and it has more chance of attracting new people)

The mod just adds names to Currently Active Users.
Is it possible to make the mod find the username & change to its usergroup color?

I edited the css to make them all the same color. Some of the names belong to users of different group. Is it possible to have the usernames actually have a specific usergroup color?

I appreciate anybody willing to help.
