The human eye contains nerve cells called cones that are capable of detecting long wavelengths (red), middle wavelengths (green), and short wavelengths (blue) of light. The brain determines the specific color that is seen by determining the ratio of the signals from the different cones. People who are "colorblind" have a defect with one or more of their cones.
