Tritan Color Blindness
Tritanomaly and tritanopia - rare blue-yellow color vision deficiencies affecting the short-wave (S) cone.
Tritan is a rare type of anomalous trichromatic vision in which the third, blue-sensitive, cones have decreased sensitivity. Less than about 0.01% of people are affected by it. However, it is known that reds and greens are unaffected, and some yellows may be visible on the lower end of the spectrum with this disorder.
