Look at the rear view mirror location!

Not 100% sure on the color names for this car, Zagato Red is also named Italian Red in some sources and I can't find the official name for the black color.
According to brochures, there is also a fifth color, but it looks black to me as well so I am not sure what it is. 90% of the 200 cars built are red, so it's difficult to find information on the other colors.
