Material is the releaser of color, and depending on the wavelength of light reflected or emitted by the material, the represented colors vary.
The richness of color presented differs based on the receiver's "translation" level of light.
Humans possess three types of receptors and can only perceive light of three colors. The colors they see are a mixture of these three colors at different shades of gray, amounting to millions. If there were four receptors, then one could see a hundred million colors.
With each additional receptor, the richness of perceived colors increases exponentially.
Compared to animals in nature that commonly have four-color vision and those with five-color perception, not to mention the mantis shrimp's exaggerated sixteen-color receptors,
mammals are somewhat less colorful, basically possessing dichromatic or trichromatic vision.
Humans are already among the best, able to experience much of nature's splendor.
