The Young-Helmholtz trichromatic model of color vision, which posits that the eye has three types of color receptors sensitive to red, green, and blue, does not fully explain why yellow appears as a primary color to most observers or why colors seem to come in complementary pairs. These observations suggest additional mechanisms of color processing beyond the initial color receptor level.
