Just go to
http://www.subaru.com/vehicles/brz/index.html and see what color you think you like. lol
I compared colors for hours before I made up my mind. I chose Satin Pearl White. I feel like the details and shape of the car are more noticable. Plus, I've drive black cars all my life and they are a pain to keep clean. Don't get SPW confused with regular White paint. The Satin finish looks awesome on this car!
My person ranking of color would be this:
1: Satin Pearl White
2. World Rally blue
3. Dark Metalic Grey
After that I'm not a fan of any of the other colors...
