A photograph color graded into orange and teal, complementary colors commonly used in Hollywood films. Color grading is a post-production process common to filmmaking and video editing of altering the appearance of an image for presentation in different environments on different devices. Various attributes of an image such as contrast, color ...
3-Way Color Grade Added filter which color grades video footage. The filter also has masking and keying tools to isolate areas of secondary color correction. Lens Blur The multi-core optimized lens blur filter emulates the circular or multi-sided iris shaped highlights that are generated with real camera lenses.
An anomaloscope requires a subject to make a color match between a mixture color and a test color. The test color is a single spectral color, for which the subject can adjust the brightness. The mixture color combines two spectral colors, for which the subject can adjust the proportion, thereby changing the hue.
Particular light frequencies give rise to sharply defined bands on the scale which can be thought of as fingerprints. For example, the element sodium has a very characteristic double yellow band known as the Sodium D-lines at 588.9950 and 589.5924 nanometers, the color of which will be familiar to anyone who has seen a low pressure sodium vapor ...
Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, and camcorders to create a color image. The filter pattern is half green, one quarter red and one quarter blue, hence is also called BGGR , RGBG , [ 1 ] [ 2 ] GRBG , [ 3 ] or RGGB .
Color matches made in the paint industry are often aimed at achieving a spectral color match rather than just a tristimulus (metameric) color match under a given spectrum of light. A spectral color match attempts to give two colors the same spectral reflectance characteristic, making them a good metameric match with a low degree of metamerism ...

A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of ...
