Colors of light can be differentiate wavelengths. The part of spectrum that is visible has range from red light with wavelength of 70 nm almost, toward violet with wavelength of 380 nm around, with orange to green, to blue and indigo between. Three different types of colors receptors in retina of human eye respond strongly to red or green or blue wavelength that actually give us an our color vision and we can see.
