CGM isn't for me but I can tell you it's pretty if you've ever been a big fan of that 'charcoal gray' on cars. It also has a bit of blue/green that sparkles out of it in the sun. Just thought i'd throw a little description out there since you hadn't seen it.
I'm sure you'll like it when you get it. Haven't heard anybody say 'ew! i hate this color!' from their car....
