DC Universe Online
You can pick a color palette of 3 different colors. You pick these colors from a color wheel.
Then you have on each armor piece (btw the look of the armor is independent from the stats but you have to acquire the armor piece to unlock the 'style') THREE areas of the piece that can be individually colored with the 3 color palette you picked out earlier. Now here's the best thing - you can not only switch which color in your palette effects which armor part ON THE FLY but also which color is in your three color palette - you guessed it - on the fly.
Also you're not paying for a single color because again - color wheel.
