then there's MY color of car. everybody calls it "green" (including garage guys), and I keep going "huh"? the closest I can find to the pain chip name actually is green "light Cyprus Green Metallic" or is that pearl, cause in bright sunlight it turns very silver, and only looks vaguely green to me (i actually thought it was "Champagne")
I think that's just the reflection of the sky on the car.
Lots of blacks have colored flake in them. Nighthawk Black Pearl (one of Honda's blacks) has blue flake. A Subaru black had blue flake also, and another has gold flake.
Looks like the M3 really is a dark blue/violet, though, instead of the metal flake giving it that look.
