- The human eye has three colour receptors, Red, Green, and Blue, each of them respond to a small section of the spectrum.
- Colors are merely signals of a particular wavelength.
- The human eye responds to the color based on their wavelength i.e it can detect green color when it senses a visible spectrum of about 530 nm and blue light if the wavelength is 450 nm.
- However, in comparison with the other spectrum, as red color has a higher wavelength i.e of about 650 nm the human eye can detect this color even from a longer distance.
