For example, Adobe RGB and sRGB are two different absolute color spaces, both based on the RGB color model. Adding a specific mapping function between a color model and a reference color space establishes within the reference color space a definite "footprint", known as a gamut, and for a given color model, this defines a color space. 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 color interpretation. When trying to reproduce color on another device, color spaces can show whether shadow/highlight detail and color saturation can be retained, and by how much either will be compromised.Ī " color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. A "color space" is a useful conceptual tool for understanding the color capabilities of a particular device or digital file. with physically realized colors assigned to a set of physical color swatches with corresponding assigned color names (including discrete numbers in – for example – the Pantone collection), or structured with mathematical rigor (as with the NCS System, Adobe RGB and sRGB). ![]() ![]() In combination with color profiling supported by various physical devices, it supports reproducible representations of color – whether such representation entails an analog or a digital representation. A comparison of the chromaticities enclosed by some color spaces.Ī color space is a specific organization of colors.
