Cats may not see as many colors as humans but have better light perception. Cats will adjust their eyes during the day, allowing less light to filter in, while their pupils will expand at night to ...
These cells detect different wavelengths of light, sending a message to the brain accordingly to be interpreted as color. "There are three types of cone cells, red, blue, and yellow.

[4] After being scratched or bitten by a cat, most dogs will become fearful of cats. [5]
Trichromatic color vision is the ability of humans and some other animals to see different colors, mediated by interactions among three types of color-sensing cone cells. The trichromatic color theory began in the 18th century, when Thomas Young proposed that color vision was a result of three different photoreceptor cells .
Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk.
Why do cats blink? As we've mentioned, we humans blink to keep our eyes in good condition. And cats do it for much the same reason – to clear away dust and debris and to keep their little ...
The dark blue, teal, and gold tapetum lucidum from the eye of a cow Retina of a mongrel dog with strong tapetal reflex. The tapetum lucidum (Latin for 'bright tapestry, coverlet'; / t ə ˈ p iː t əm ˈ l uː s ɪ d əm / tə-PEE-təm LOO-sih-dəm; pl.: tapeta lucida) [1] is a layer of tissue in the eye of many vertebrates and some other animals.
Certain colors do not have significant effect, however; any hue of colored lights still seem brighter than white light of the same brightness. Two colors that do not have as great of an Helmholtz–Kohlrausch effect as the others are green and yellow. [2] The Helmholtz–Kohlrausch effect is affected by the viewing environment.
