Dogs do not have red-sensing cones, so their sight is similar to that of someone with red-green color blindness, according to research by Jay Neitz, a professor of ophthalmology and a color vision ...
Blindness in animals can be caused be the result of environmental adaptations over time, or due to various conditions of the eyes. [1] Many blind species have been able to adapt, [2] navigate and survive in their environment by relying on their other senses.
The basis for this variation is the number of cone types that differ between species. Mammals, in general, have a color vision of a limited type, and usually have red–green color blindness, with only two types of cones. Humans, some primates, and some marsupials see an extended range of colors, but only by comparison with other mammals.
Monochromacy (from Greek mono, meaning "one" and chromo, meaning "color") is the ability of organisms to perceive only light intensity without respect to spectral composition. Organisms with monochromacy lack color vision and can only see in shades of grey ranging from black to white. Organisms with monochromacy are called monochromats.
Cats' vision is not black and white. Here's the truth about whether cats can see color—and how their vision differs from ours in other ways. The post Can Cats See Color? appeared first on Reader ...
For red-and-green, some saw an even field of the new color; some saw a regular pattern of just-visible green dots and red dots; some saw islands of one color on a background of the other color.

An issue with color selection is that the colors with the greatest contrast to the red–green color blind tend to be colors of confusion to the blue–yellow color blind and vice versa. In 2018, UX designer Allie Ofisher published 3 color palettes with 6 colors each, distinguishable for all variants of color blindness.
