Human color representation utilizes three RGB channels due to retinal cone physiology
the verdict
SUPPORTED
the evidence backs this
confidence 87/100
Human trichromatic color vision and its three channels are directly grounded in the physiological presence of three distinct classes of cone photoreceptors in the retina.
