Young and Helmholtz's trichromatic theory states that any color in the spectrum can be matched by combining three other wavelengths. This theory is based on experiments that show that the human visual system has three types of cones that are sensitive to different wavelengths of light. When these cones are stimulated in different combinations, they can create the perception of any color.
