Knowra Color model Color model A color model represents colors as coordinates in a defined system, such as RGB or CMYK. Its coordinates describe colors but do not, by themselves, fully specify their appearance.
Color space : A defined range of colors with a coordinate system and rules for interpreting its coordinates. A model supplies coordinates; a color space specifies how those coordinates map to colors.
RGB color model : An additive color model that represents colors as combinations of red, green, and blue channel values. It models light emitted by displays and other electronic imaging systems.
sRGB : A standard RGB color space widely used for web content and consumer displays. It gives RGB coordinates a common, bounded interpretation across ordinary digital content.
Additive color : Color formation by combining emitted light, with stronger contributions generally producing greater brightness. RGB models encode this mixing process, unlike models for reflective inks.
Colorimetry : The science of measuring and specifying color through physical and perceptual quantities. Color models draw on colorimetry to relate numerical coordinates to measured color.
CMYK color model : A subtractive color model that represents printing colors using cyan, magenta, yellow, and black inks. It translates color into ink amounts, where pigments absorb rather than emit light.
Adobe RGB color space : A wide-gamut RGB color space developed for digital imaging and print workflows. Its larger gamut than sRGB serves workflows that need more printable saturated colors.
Subtractive color : Color formation as pigments or filters absorb portions of incident light. CMYK models approximate this process, which differs physically from additive RGB mixing.
Tristimulus values : Three values that match a color by combining three primaries under a specified observer and illuminant. Many models begin with three-coordinate representations grounded in color matching.
HSL and HSV : Cylindrical transformations of RGB coordinates using hue, saturation, and lightness or value. These models reorganize RGB coordinates into controls that are convenient for color selection.
