Color Color Color (American English), or colour (Commonwealth English), is the characteristic of human visual perception described through color "categories", with names such as red, orange, yellow, green, blue, or purple. This perception of color derives from the stimulation of cone cells in the human eye by electromagnetic radiation in the visible spectrum. Color categories and physical specifications of color are associated with objects through the wavelength of the light that is reflected from them. This reflection is governed by the object's physical properties such as light absorption, emission spectra, etc. By defining a color space, colors can be identified numerically
American anthropology future behavior; and they cooperate in problem-solving. Nevertheless, the term "culture" applies to non-human animals only if we define culture as any or all learned behavior. Within mainstream physical anthropology, scholars tend to think that a more restrictive definition is necessary. These researchers are concerned with how human beings evolved to be different from other species. A more precise definition of culture, which excludes non-human social behavior, would allow physical anthropologists to study how humans evolved their unique capacity for "culture". Chimpanzees ("Pan troglodytes" and "Pan paniscus") are humans' ("Homo sapiens") closest living relatives; both are descended from a common
