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.
Exploration of the color space outside the range of "real colors" by this means is major corroborating evidence for the opponent-process theory of color vision. Chimerical colors can be seen while seeing with one eye or with both eyes, and are not observed to reproduce simultaneously qualities of opposing colors (e.g. "yellowish blue"). [4]
Today, most mammals possess dichromatic vision, corresponding to protanopia red–green color blindness.

Congenital red–green color blindness - partial color blindness include protanopia, deuteranopia, etc. Oligocone trichromacy - poor visual acuity and impairment of cone function according to ERG, [expand acronym] but without significant color vision loss. [15] Bradyopsia - photopic vision cannot respond quickly to stimuli. [15]
"They see color via special photoreceptive cone cells in the backs of their eye (retina), just like we do. These cells detect different wavelengths of light, sending a message to the brain ...
