San Marino Blue

San Marino Blue has been a relatively popular color on M cars, it also featured as the communication color for the F06 M6 and was one of the standard colors for the M3 CS and M4 CS.

Visually it looks pretty similar to the more recent Marina Bay Blue when comparing images, although in person you'll notice San Marino is a much deeper blue with a strong metallic flake under the sun. It also has a slightly purple hue to it which is more noticeable when comparing it directly to other blue colors.
