Deuteranomaly

Deuteranomaly is apparently the most common type of colour blindness. According to Wikipedia: "These individuals have a mutated form of the medium-wavelength (green) pigment. The medium-wavelength pigment is shifted towards the red end of the spectrum resulting in a reduction in sensitivity to the green area of the spectrum." Which means that these people have problems differentiating between red and green. The following photograph was taken at the Coys International Historic Festival meeting at Silverstone in July 1999.
Both cars were built (early 1930s and early 1960s) at a time when, by and large, racing cars were painted in their national racing colours. The green car is an Italian (racing colours: red) Alfa Romeo 8C 2300 Monza, and the red car is a British (racing colours: green) Aston Martin DB4 GT Zagato.

  1. There is a feature article about the Alfa in the July 1994 edition of Classic Cars magazine, which shows it painted red. The article notes that it was variously red and green at different times in its life.
