XF 2.1 Username Styled by Secondary Group but Inherit primary group color?


Hey there,

Just reaching out to anyone who knows how this can be achieved through some settings/setup in XenForo or even an addon? The title sort of explains it all already.
Let me elaborate a bit further on my questions. Is it possible have custom CSS styling done to secondary groups, but still have the user inherit his username color from his primary group?

I'm an administrator so my username is Red across the board.
I then buy access to VIP on my forum.
Now I'm placed into a VIP access-group where the CSS styling makes my name Italic or Bold, but still keeps my name Red.
