White's a bit on the loud side, but I've always been a fan. Would get white wheels myself if I had a drive way and more opportunities to clean the car. 16s however is too small in my opinion. The wheels will shout "hey look at my sporty stylings" but the 16" rim will look small in the wheel arch and therefore look a little silly. In my opinion, if you're going to for an eye catching colour, it will look best in 17" or larger.
