Can someone help me with a CSS code to put the usergroup's colour in Latest Topics?

[Ninja04]

I'm using VB 5.5.3, my latest topics module is not colouring the usernames by the usergroup colour as rest of the forums do (i guess the CSS code i got is used only for forums and subforums)

/* Forum & Subforums Coloured START */

.forum23 .forum-title {color:red}

.b-post__footer div[id^=content-tags] {
    display: none;
}
/*FORUM & SUBFORUMS COLOURED END*/
