Humans perceive different colors of visible light primarily by their wavelength. The visible spectrum consists of light with wavelengths approximately ranging from 380 nanometers (violet) to about 750 nanometers (red). Our eyes contain photoreceptors that are sensitive to specific ranges of wavelengths, and these receptors contribute to our perception of different colors. While frequency and energy are related to wavelength (since higher frequency corresponds to shorter wavelength and higher energy), it is the wavelength that directly correlates with the colors we perceive.
