Man, colors are so subjective. OS was at the bottom of my list and I ended up on an Alpine white which I think shows the lines best on the car but I'm sure the previous poster with the OS thinks his does. I bought a yellow Gallardo which looks fantastic in that color but I do not like the new yellow on the Z4 at all. It's funny how some cars look great in one color and another car looks better in a totally different color. In the end you just have to please yourself!
