Spectral color information

A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible...

thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell...

colors. The original color circle of Isaac Newton showed only the spectral hues and was provided to illustrate a rule for the color of mixtures of lights...

for color calibration. Accurate color profiles ensure consistency throughout the imaging workflow, from acquisition to output. The absolute spectral power...

The term "indigo" can refer to the color of the dye, various colors of fabric dyed with indigo dye, a spectral color, one of the seven colors of the rainbow...

the United States refer to the blue-dominated spectral color beyond blue as purple, but the same color is referred to as violet by many native English...

pigment protein – that have different spectral sensitivities. Humans contain three types, resulting in trichromatic color vision. Each individual cone contains...

details), three spectral bands are commonly combined into a false-color image. At least two spectral bands are needed for a false-color encoding, and it...

textbooks of color theory, and depending on the geographical-cultural origin of the author, a "purple" is defined as any non-spectral color between violet...

of the color wheel. Scientifically derived color schemes (or scientific color maps) seek to improve on traditionally color schemes (spectral schemes...

violet. The blue-dominated spectral color beyond blue is referred to as purple by many speakers in the United States, but this color is called violet by many...

In radiometry, photometry, and color science, a spectral power distribution (SPD) measurement describes the power per unit area per unit wavelength of...

identified as the color's dominant wavelength if the point is on the same side of the white point as the spectral locus, and as the color's complementary...

possible light spectrum. No physical object can have an imaginary color. The spectral sensitivity curve of medium-wavelength ("M") cone cells overlaps...

of color. It serves as a standard reference against which many other color spaces are defined. A set of color-matching functions, like the spectral sensitivity...

extra-spectral color, meaning that it is not a hue associated with monochromatic visible light. Magenta is associated with perception of spectral power...

characterizations such as spectral sensitivity are therefore quite useful in describing many properties of color vision. Spectral sensitivity is sometimes...

Subtractive color or subtractive color mixing predicts the spectral power distribution of light after it passes through successive layers of partially...

Color blindness or color vision deficiency (CVD) is the decreased ability to see color or differences in color. The severity of color blindness ranges...

An asteroid spectral type is assigned to asteroids based on their reflectance spectrum, color, and sometimes albedo. These types are thought to correspond...

In color theory, the line of purples or purple boundary is the locus on the edge of the chromaticity diagram formed between extreme spectral red and violet...
