TIL about Tetrachromacy, a condition which lets you see more colors. Normal people can see about 1 million colors, while tetrachromats may see up to 100 million. Up to 12% of women may have it. (www.healthline.com)

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
