HCL (Hue-Chroma-Luminance) or LCh refers to any of the many cylindrical color space models that are designed to accord with human perception of color with the three parameters. Lch has been adopted by information visualization practitioners to present data without the bias implicit in using varying saturation. They are, in general, designed to have characteristics of both cylindrical translations of the RGB color space, such as HSL and HSV, and the L*a*b* color space. Some conflicting definitions of the terms are:

- Beim CIE-LCh-Farbraum handelt es sich um den CIELab-Farbraum, wobei anstelle der kartesischen Koordinaten a* und b* die Zylinderkoordinaten C* (relative Farbsättigung, englisch chroma ‚Buntheit‘) und h° (englisch hue angle ‚Farbtonwinkel‘) angegeben werden. Die Farbhelligkeit L* (englisch lightness ‚Helligkeit‘) bleibt dabei unverändert. Für diesen Farbraum sind die vereinfachten Schreibweisen LCh, LCH und HLC (Farbton H – Helligkeit L – Sättigung C) gebräuchlich. (de)

Some conflicting definitions of the terms are:
* A name for a cylindrical transformation of CIELuv (CIELChuv) employed by Ihaka (2003) and adopted by Zeileis et al. (2009, 2020). This name appears to be the one most commonly used in information visualization. Ihaka, Zeileis, and co-authors also provide software implementations and web pages to promote its use.
* A name for cylindrical CIELab (CIELChab), employed by chroma.js.
* "HCL" designed in 2005 by Sarifuddin and Missaou, which is a transformation of whatever type of RGB color space is in use. (en)
