Why are cones most sensitive to red green and blue?

Cones are photoreceptor cells in the retina that are sensitive to different wavelengths of light, corresponding to red, green, and blue colors. This sensitivity is due to the presence of specific photopigments in each type of cone: L-cones for long wavelengths (red), M-cones for medium wavelengths (green), and S-cones for short wavelengths (blue). The combination of signals from these three types of cones enables the brain to perceive a wide range of colors through a process called color vision. This trichromatic system is fundamental for distinguishing colors in our environment.
