Humans are trichromats, meaning we perceive three primary colours: blue, green and red. The retina in a human eye can detect light between wavelengths of 400 nanometres (lowest-violet) and 700 nanometres(highest-red), a range known as the visible spectrum.
In the middle of the spectrum resides the colour green(around 555 nanometres). This wavelength is where our perception is at its best. Because of its position in the center of the spectrum, both violet and red light waves are enhanced and better perceived with the help of green waves.
