Dichromatic vision in animals
WebColor vision in the retina: Humans have three types of color cones in our retinas. We have "trichromatic" vision, consisting of short-wavelength "blue" cones, middle-wavelength "green" cones and long-wavelength "red" cones. Rats have just two types of cones (called "dichromatic" vision): a short "blue-UV" and the middle "green" cones (Szel 1992). WebAnimals were also trained to respond to the colored increments when paired with the white increment when both were at equally detectable intensities. ... This high color-vision …
