How many colors can we see?

It’s a colorful world out there! When light from the sun hits surfaces on Earth, those surfaces reflect different wavelengths of light. Our eyes collect those waves and send them to our brains, which interpret the waves as colors! It’s an incredible process, and it happens in…well, the blink of an eye. But how many different colors can our eyes and brains identify? We asked University of Leeds color science professor Stephen Westland to help us find the answer. Got a HUE-mungous question? Send it to us at BrainsOn.org/contact, and we’ll identif-EYE the answer. See omnystudio.com/listener for privacy information.
