His color system is based on artistic understanding of light rather than the prismatic colors used in wheels or bars of color, or the artist-based trichromatic theories that inspired Mayer, although he includes them both in his form.    From Wordnik.com.  [The Creation of Color in Eighteenth-Century Europe] Reference

Whereas humans have trichromatic vision corresponding to the three different kinds of photoreceptor cells we have in our retinas that allows us to see light in a relatively narrow range we call the "visual spectrum," the mantis shrimp has four times as many kinds of photoreceptors that allow it to see a much broader spectrum of light, including polarized light.    From Wordnik.com.  [Animal Eyes] Reference

The trichromatic ideal was explained by Jacob Christoph Le Blon, used by Charles-François Dufay, adjusted by Jacques-Fabien Gautier and Louis-Bertrand Castel, made visible by Tobias Mayer, Moses Harris, Johann Heinrich Lambert and others. reference reference reference reference The concept, its connections to theory more or less intact, was included in presentations of practical advice about color production and color use for many different specialties.    From Wordnik.com.  [The Creation of Color in Eighteenth-Century Europe] Reference
