For a given target, MacAdam ellipses define zones of Gaussian standard deviations around which this quality is indistinguishable. The R9 value extends an index named for this quality. The 1976 version of a diagram depicting this quality transformed the more commonly used 1931 version from X-Y-Z coordinates to L-u-v coordinates. Iso lines for this quality are perpendicular to Planckian loci on those diagrams, published by the CIE. A namesake (*) rendering index quantifies how well a light source reproduces this quality, as compared to blackbody emission. The Kelvin temperature of a light source is more commonly known as this quality's temperature. Popular specifications of this quality include HSV, CMYK, and RGB. For
