👉 Tesserants, also known as tetrachromats or trichromat, are a type of photoreceptor cells found in the retina and pigments that can be detected by a variety of different methods. These cells contain two types of pigments: tetrachromes (or trichromes) which have an array of three different wavelengths of light, and chromophores (chromatic pigments), which are more specific to each wavelength. Tesserants typically produce
