Understanding Blue-Yellow Color Blindness
Blue-yellow color blindness (Tritanopia/Tritanomaly) is much rarer than red-green color blindness, affecting less than 0.01% of the population. Unlike red-green deficiency, it affects men and women equally.
Tritanopia
Complete blue-yellow color blindness. Blues may appear greenish, and yellows may appear violet or light gray.
Tritanomaly
Reduced blue sensitivity. Colors may appear slightly shifted, with difficulty distinguishing blue from green.
Blue-yellow color blindness can be inherited or acquired later in life due to age-related changes, certain medications, or eye conditions.
