CIELAB is an option in Digital Color Meter on macOS described as "L*a*b*". CIELAB is available in the RawTherapee photo editor, where it is called the "Lab color space". CIELAB is used by GIMP for the hue-chroma adjustment filter, fuzzy-select and paint-bucket. There is also a LCh(ab) color picker. See more The CIELAB color space, also referred to as L*a*b*, is a color space defined by the International Commission on Illumination (abbreviated CIE) in 1976.

The L, M, and D colors within each Munsell hue were equivalent in Munsell chroma (saturation). This set comprised the 32 chromatic colors that were studied (see Fig. 1).
WebCIELAB and CIELUV were primarily suggested to provide color-difference equations but they were also designed to express color differences correlated with perception attributes: hue, lightness, and chroma. These spaces are represented by plotting the three attributes along axes at right angles to one another.
