Color Vision Explained

Color Vision Explained

The human eye perceives different shades of color by the use of rods and cones located in the retina. Color vision is dependent on the object that is reflecting a certain hue and the person perceiving it.

The human eye’s rods are used to distinguish light colors from dark colors. On the other hand, cones are used to help distinguish shades of color. A human eye that is able to perceive colors contains three cones that are used to view variations of green, red and blue.

Each of the eye’s cones perceives color wavelength. There are some colors that are perceived using a combinations of cones that contain a mixture of two light wavelengths, like green and yellow. The visual information that is received is then sent to the brain, which conveys what colors are being perceived.

Not all individuals views colors in the same way for a variety of reasons. In part, this is due to variations of color blindness as well as variations between one individual’s set of cones compared to another. Color vision is dependent on how a person sees an object, how light is reflected off an object and how the eye perceives it.
