Tired of mages and shamans being the same color? (Damn right)
Think paladins should have a more manly color then pink? (You're totally wrong)
Here is an addon that lets you customize it quickly and easily.
This Ace2 AddOn simply manipulates the RAID_CLASS_COLORS array allowing you to customize the display color of every class in any mod that makes use of the defines.
Simply /classcolors config (or /cc config) to pop up a menu providing a color wheel of selecting your favorite color.
