Blindness Color Testing
|
Color blindness - Color blindness, or color vision deficiency, in humans is the inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.
Color agnosia - Color agnosia (agnosia: Greek for non-knowledge) is a medical or psychological condition that prevents a person from recognizing colors (even though the eyes are capable of distinguishing them). It is a specific form of agnosia, and generally results from damage to the visual cortex, often in V4 (as opposed to most other kinds of color blindness, which derive from photoreceptors.
Arthur König - Arthur König (1856–1901) was a student of Helmholtz who studied human color vision and color blindness. He proposed that dichromacy, the most common form of color blindness, was from the absence of one of the three "fundamental sensations" (now known as cone photopigments).
Primary color - A primary color (or colour) is a color that cannot be created by mixing other colors in the gamut of a given color space. Primary colors may themselves be mixed to produce most of the colors in a given color space: mixing two primary colors produces what is generally called a secondary color, mixing a secondary with a primary produces what is sometimes called a tertiary color.
