color /col·or/ (
kul´er)
1. a property of a surface or substance due to absorption of certain light rays and reflection of others within the range of wavelengths (roughly 370–760 mμ) adequate to excite the retinal receptors.
2. radiant energy within the range of adequate chromatic stimuli of the retina, i.e., between the infrared and ultraviolet.
3. a sensory impression of one of the rainbow hues.
complementary colors a pair of colors the sensory mechanisms for which are so linked that when they are mixed on the color wheel they cancel each other out, leaving neutral gray.
confusion colors different colors liable to be mistakenly matched by persons with defective color vision, and hence used for detecting different types of color vision defects.
primary colors a small number of fundamental colors;
(a) in visual science, red, green, and blue, the colors specifically picked up by the retinal
cones;
(b) in painting and printing, blue, yellow, and red.
pure color one whose stimulus consists of homogeneous wavelengths, with little or no admixture of wavelengths of other hues.
col·or (k l  r)n.1. That aspect of the appearance of objects and light sources that may be specified in terms of hue, lightness, and saturation. 2. That portion of the visible electromagnetic spectrum specified in terms of wavelength, luminosity, and purity. 3. The general appearance of the skin. 4. The skin pigmentation of a person not classified as white. |

broken colorin decribing coat color, a solid color broken up by another color, usually white.
color dilutionreduction of the concentration of the color pigment in tissue; most important in hair and other fiber coats, in the skin and in the ocular iris.
color pigmentsthe pigments influencing skin color are melanin, melanoid, oxygenated hemoglobin, reduced hemoglobin, carotene.
color visionthe domestic animal species have limited color vision, the best perception being in bright light. Birds probably have the best, cattle and sheep the least, if any.
Patient discussion about colors.
Q. If someone as alcoholism do there eyes change color? My husband says his work mate told him that if you’re an alcoholic your eyes can change color. As an example If you have blue eyes they become a darker blue because of something in your bloodstream?. I think my husband’s workmate is winding my husband up, or is he telling the truth?
A. That is an untruth. The color of the eyes in an alcoholic will not change color. The only thing in the eyes that will change color are the corneas (the whites of the eyes) they will turn yellow due to jaundice and probably cirrhosis of the liver. The skin will also turn yellow with the jaundice.
Q. What exactly is PPD? I heard it is a substance in hair color and that some women are allergic to it How can I know if I’m allergic to it?
A. That sounds nasty... so how can I know if i'm allergic to it or not?
Q. Why is the color draining from my eyes?! When I was little I had rich shiny cobalt blue eyes! As I grew up they faded or just started to dim in color. Being partially blind you can see in my left eye the its a really light color and creamy instead of my deep blue color... Why does my eye color dim?! I didnt think going blind had anything to do with the color of my eyes changing... Or is it something else?! Please, and thank you!
A. depends on your blindness, if it is caused by your cornea changing (corneal opacity)- it'll change your eye color to a cloudy white. it can also be caused by cataract.
are those the reason of your blindness?
