Color RealID whispers by class?

[Wimpface]

Google searched yielded nothing but ElvUI and ShestakUI links.

I'm looking for a standalone addon that colors RealID whispers by class. RealID whispers aren't that confusing to tell apart because they use real names, but Battle Tags really get to me for some reason. Many times now have I sent a whisper to the wrong person because I'm whispering different battle tags and they're all similar length and same color. Just coloring the name would go a long way for me.

Does anyone know if such an addon exists?
