Answer;
Opponent process theory 
Explanation; 
-Opponent process theory suggests that color perception is controlled by the activity of two opponent systems: a blue-yellow mechanism and a red-green mechanism.
-The opponent process theory suggests that the way humans perceive colors is controlled by three opposing systems. We need four unique colors to characterize perception of color: blue, yellow, red, and green.

The human body can’t live without the good functions of cells.
And to be more concise, proteins are the major part of cells. Where there is a cell, there is a protein or more.
