Color vision begins with the photoreceptors (which are sensors in the back of our eyes that turn light into electrical signals in the brain allowing us to perceive color). Many people have three different kinds of photoreceptors (sensitive to blues, greens and reds). The photoreceptors combine in order for us to see the full range of colors.
While color blindness is a fairly common problem affecting nearly 8 percent of men and 1 percent of women, there is also such thing as the ability to see more color. This is called tetrachromats meaning that they possess four color receptors versus three and makes them more sensitive to color.
