Cone cells contain opsins which cause us to see the color blue. So, when someone does not have these opsins, they cannot distinguish green from blue. People with Tritanopia also confuse yellow and violet.
What is the difference between tritanopia and tritanomaly?
If you have tritanopia, you are missing a type of cone cell called S-cones. S-cones are short-wavelength cones. With tritanomaly, S-cones are present, but they are functionally limited. People see blues as greener and the colors yellow and red seem pink. With this type of color blindness, the intensity depends on the functionality of the S-cones.
