Why do you see more than 3 colors?

Humans typically see more than three colors because our eyes contain three types of cone cells, each sensitive to different wavelengths of light: short (blue), medium (green), and long (red). The brain processes signals from these cones to create a wide spectrum of colors through a process called color mixing. Additionally, factors like lighting conditions, surrounding colors, and individual differences in vision can enhance our perception of color variety. This ability allows us to see millions of colors by combining the inputs from these three types of cones.
