Summary
We perceive colors when light is reflected off an object's surface. The object absorbs all other wavelengths and reflects the ones we see as color. For example, an apple appears red because it reflects the wavelengths we see as red and absorbs all the others.

Summary
Color helps us remember objects, influence our purchases, and sparks our emotions, but it is also important to know that objects do not possess color. The retina has two different types of cells that detect and respond to light—rods and cones—which contain photo pigments and are stimulated in brighter environments. Color blindness can occur when one or more of the cone types are not functioning as expected, and men are more likely to have color blindness than women.
