How Many Colors Can We See?

The video explains how color perception varies due to the number and type of cone receptors in the eyes. Most humans have three types of cones, allowing them to see about one million colors. Color blindness occurs when one or more cone types are missing, affecting color distinction. The video also discusses the genetic basis of color vision, noting that color blindness is more common in males due to its linkage to the X chromosome. Additionally, some women may have a fourth type of cone, enabling them to perceive up to 100 million colors, a condition known as tetrachromacy.
