Abstract
The spectral reflectance curves of 433 chips in the Munsell Book of Color have been found to depend on only three components which account for 99.18% of the variance. It is suggested that this three-component dependency may be a characteristic of all organic pigments, including those in the retina, and thus explain the trichromatic nature of color vision.
