Changing navtab color and forum title color?

[SPEEDKILLZ]

I am trying to change the color of my selected navtab color from blue to #2e2f39 i want to leave all other colors of it the same. I have looked thru the stylvar think it was navbabr tab_selected color but it did nothing i have also tried

#vbtab_forum a.navtab {
    background-color: #2e2f39;
    color: #FBCB3D
}
#vbtab_what's new a.navtab {
    background-color: #2e2f39;
    color: #FBCB3D
}
#vbtab_classifieds a.navtab {
    background-color: #2e2f39;
    color: #FBCB3D
}
#vbtab_garage a.navtab {
    background-color: #2e2f39;
    color: #FBCB3D
}
#vbtab_gearbanging media a.navtab {
    background-color: #2e2f39;
    color: #FBCB3D
}

with no luck any other suggestion?

I would also like to change the text color of the forum name and last post color to #2e2f39 but cannot seem to find it either.

Any help would be great. Thank you
