In color science, a color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three...

The RGB color model is an additive color model in which the red, green, and blue primary colors of light are added together in various ways to reproduce...

The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and...

subtractive color model used in art and applied design in which red, yellow, and blue pigments are considered primary colors. Under traditional color theory...

Blackness) is a cylindrical-coordinate representation of points in an RGB color model, similar to HSL and HSV. It was developed by HSV’s creator Alvy Ray Smith...

A color appearance model (CAM) is a mathematical model that seeks to describe the perceptual aspects of human color vision, i.e. viewing conditions under...

types of color mixing models, depending on the relative brightness of the resultant mixture: additive, subtractive, and average. In these models, mixing...

A secondary color is a color made by mixing two primary colors of a given color model in even proportions. Combining two secondary colors in the same...

Like the CIEXYZ space it derives from, CIELAB color space is a device-independent, "standard observer" model. The colors it defines are not relative to any...

colors can be organized in a color space, which when being abstracted as a mathematical color model can assign each region of color with a corresponding set...

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...

An RG color model is a dichromatic color model represented by red and green primary colors. These can only reproduce a fraction of the colors possible...

Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining...

RGB color spaces are a category of additive colorimetric color spaces specifying part of its absolute color space definition using the RGB color model. RGB...

Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the...
