Obviously, paint choice is a very personal preference. The reason you don't care for the metallic blue (is it black or is it blue), is exactly the reason i love the color. It seems to have more of a "personality" that changes depending on weather conditions and lighting.
The Ocean blue to me(only pictures so far) appears to be always blue, no color shifting. So i prefer the metallic blue.
Anyway, to those who wanted a lighter Blue, now is your chance to get the car of your dreams, that is better than you currently imagine it will be, and will get better over time.
