According to Deeb (2005), there are two relatively common types of causes for tetrachromacy in humans: The common Ser180Ala polymorphism, which results in two spectrally different red pigments in the retina.

Previously they said you can’t test for it with normal computer screens but it seems they found something out about how tetrachromats process the red blue yellow colors everyone else sees, that gives them away as tetrachromats without requiring them to leave home.

Tetrachromacy causes people to a. be more sensitive to blue light b. see perfectly in the dark c. distinguish more colours than the average person; Tetrachromacy has only been found in a. women b. young children c. artists; Scientists test for tetrachromacy by a. taking a DNA sample b. observing a person’s reactions to bright light

Tetrachromacy is the possession of four cone cells. This allows organisms to have a four-dimensional color experience—something that fish, reptiles, and diural birds all have.

See full list on healthline.com Tetrachromatic color vision here refers to human color vision that relies on the presence of four types of retinal cone photopigment whose signals are processed independently.The Ishihara plates test is one of the most established and widely used means of identifying color vision deficiencies.
