Answer 1

In your eyes are special cells called “cones” of which there are three types. Each cone responds to different wavelengths of light, roughly: red, green, and blue.

The colors you perceive are just electrochemical signals sent to your brain from those cones and those cones are activated by different intensities of red, green, and blue wave lengths.
