Question: What can you see if you have tetrachromacy?
Answer: Tetrachromacy is a rare genetic condition that allows a small percentage of women to distinguish differences among nearly 100 million shades of color, compared to the one million colors people with normal vision can see. The condition is linked to the X chromosome and involves a fourth cone type in the eye, granting superior color discrimination. It’s not that people with tetrachromacy can see new colors, it’s that they can perceive finer distinctions between very similar colors.
