Color vision distinguishes distributions of visible light across wavelengths through the different spectral sensitivities of visual receptors. A perceived colour need not correspond to one wavelength: different optical spectra can produce the same receptor responses. Consequently the broad spectral filtering of thin-film interference need not produce pure monochromatic colours.

Color vision is the capacity of the visual system to perceive and distinguish different colors. This ability arises from the way the human eye and brain process light. The retina, located at the back of the eye, contains photoreceptor cells known as cones, which are responsible for color detection. There are three types of cones, each sensitive to different wavelengths of light corresponding to red, green, and blue colors.
