Tetrachromacy is a rare eye condition that allows for increased color vision. We’ll tell you about what causes it and how it’s diagnosed, as well as why you need to be skeptical of online tests.
According to wikipedia, tetrachromacy is caused by having having both normal vision and red-green color blind genes in different chromosomes, so some of the red or green cones end up being receptive to a wavelength between red and green. Rods don’t sound affected.
Health line article doesn’t mention the wavelength. Got me excited that it was infrared or something
