Bayer filter A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern… Bayer filter
Afterimage An afterimage is an image that continues to appear in one’s vision after the exposure to the original image has ceased. An afterimage may be a normal phenomenon (physiological afterimage) or may be pathological (palinopsia). Illusory palinopsia may be a pathological exaggeration of physiological afterimages. Afterimages occur because photochemical activity… Afterimage
Additive color Additive color is a method to create color by mixing a number of different light colors, with shades of red, green, and blue being the most common primary colors used in additive color system. Additive color is in contrast to subtractive color, in which colors are created by subtracting (absorbing)… Additive color
Eye color Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye’s iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending… Eye color
Colors of the rainbow The rainbow effect is also commonly seen near waterfalls or fountains. In addition, the effect can be artificially created by dispersing water droplets into the air during a sunny day. Rarely, a moonbow, lunar rainbow or nighttime rainbow, can be seen on strongly moonlit nights. As human visual perception for… Colors of the rainbow
Colorimetry Colorimetry is “the science and technology used to quantify and describe physically the human color perception.” 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.… Colorimetry
Color psychology Color psychology is the study of hues as a determinant of human behavior. Color influences perceptions that are not obvious, such as the taste of food. Colours can also enhance the effectiveness of placebos. For example, red or orange pills are generally used as stimulants. Colour can indeed influence a… Color psychology
Kruithof curve The Kruithof curve describes a region of illuminance levels and color temperatures that are often viewed as comfortable or pleasing to an observer. The curve was constructed from psychophysical data collected by Dutch physicist Arie Andries Kruithof, though the original experimental data is not present on the curve itself. Lighting… Kruithof curve
Eigengrau Intrinsic gray (German: Eigengrau), also called Eigenlicht, own light, dark light, or brain gray, is the uniform dark gray background that many people report seeing in the absence of light. At that time it was noticed that with very large as well as very small brightnesses the sensitivity of the… Eigengrau
Correlated color temperature The correlated color temperature (CCT, Tcp) is the temperature of the Planckian radiator whose perceived color most closely resembles that of a given stimulus at the same brightness and under specified viewing conditions — CIE/IEC 17.4:1987, International Lighting Vocabulary (ISBN 3900734070) Motivation Black-body radiators are the reference by which the whiteness… Correlated color temperature
Color temperature The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of a color comparable to that of the light source. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, horticulture, and other… Color temperature

Amber color The color amber is a pure chroma color, located on the color wheel midway between the colors of gold and orange. The color name is derived from the material also known as amber, which is commonly found in a range of yellow-orange-brown-red colors; likewise, as a color amber can refer… Amber color
Amazon color Amazon is one of the colors of Jungle green. The first recorded use of amazon as a color name in English was in 1924. Color coordinates Hex triplet #3B7A57 RGB (r, g, b) (59, 122, 87) CMYK (c, m, y, k) (80, 31, 75, 17) HSV (h, s, v) (147°,… Amazon color
Almond color Almond is one of the colors of Crayola crayon colors. Since the introduction of Crayola drawing crayons by Binney & Smith in 1903, more than two hundred distinctive colors have been produced in a wide variety of assortments. Color coordinates Hex triplet #EED9C4 RGB (r, g, b) (238, 217, 196)… Almond color
