Color vision results from the combination of signals from three visual pigment types within cones: that of red, green, and blue, which correspond to cone types L, M, and S (RGB-LMS). Those colors correspond to the wavelengths of peak light absorption intensities of the modified chromophores. L cones have peak absorptions at 555 nm to 565 nm, M ...
