Why Do Some People See Colors Differently Than Others?

Some people see colors differently because their eyes have special little sensors called cones. Cones are like tiny color detectors in the eye, they catch light and send messages to the brain. Some people have more of one type of cone, or even extra ones! That’s why some people might see a lot more shades than others do.
