The three-dimensional space that is defined by a set of coordinates for representing color on devices such as monitors, scanners, and printers. For example, in the LAB color space, the colors are defined in terms of their luminance or whiteness (L), redness-greenness (A), and yellowness-blueness (B); the HVC system uses hue (H), value (V), and chroma (C). The two most common color space models are RGB and YUV.
