Color reproduction is an aspect of color science concerned with producing light spectra that evoke a desired color, either through additive (light emitting) or subtractive (surface color) models. It converts physical correlates of color perception ( CIE 1931 XYZ color space tristimulus values and related quantities) into light spectra that can ...
Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.
In herbivorous primates, color perception is essential for finding proper (immature) leaves. In hummingbirds, particular flower types are often recognized by color as well. On the other hand, nocturnal mammals have less-developed color vision since adequate light is needed for cones to function properly. There is evidence that ultraviolet light ...
Color meaning is either based in learned meaning or biologically innate meaning. The perception of a color causes evaluation automatically by the person perceiving. The evaluation process forces color-motivated behavior. Color usually exerts its influence automatically. Color meaning and effect has to do with context as well. [12]
Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. [3]
Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
The new collection includes a special oversized handknit scarf using “The King’s Clip”, a unique yarn developed for the first time from the fleeces of three flocks of sheep kept at Dumfries ...
Primates, as an order of mammals, began to emerge around the beginning of the Paleogene Period. Primates have re-developed trichromatic color vision since that time, by the mechanism of gene duplication , being under unusually high evolutionary pressure to develop color vision better than the mammalian standard.
