Detailed explanation-1: -The cone cells come in three varieties: red-detecting, green-detecting, and blue-detecting. They are so named because the red cone cells mostly detect red light, the green cone cells mostly detect green light, and the blue cone cells mostly detect blue light.

Detailed explanation-2: -Red, green, and blue are known as the primary colors of light. The combinations of two of the three primary colors of light produce the secondary colors of light. The secondary colors of light are cyan, magenta, and yellow.

Detailed explanation-3: -The colors red, green, and blue are classically considered the primary colors because they are fundamental to human vision. All other colors of the visible light spectrum can be produced by properly adding different combinations of these three colors.

Detailed explanation-4: -Scientists have known for decades that some cells-known as cones-detect color. They are part of the retina inside the back of the eye. Cone cells can sense red, green or blue light.
