Differences in wavelength of light are responsible for the perception of color. If the human eye was not responsive to these differences, we would not be able to perceive color. Brightness and saturation are also dependent on differences in wavelength, but to a lesser extent than color. Purity is not directly related to wavelengths of light, but rather to the absence of other wavelengths.
