Lch has been adopted by information visualization practitioners to present data without the bias implicit in using varying saturation.
[9] CIE-based LCh color spaces are transformations of the two chroma values (ab or uv) into the polar coordinate.
Sarifuddin, noting the lack of blue hue consistency of CIELAB—a common complaint among its users—[10] decided to make their own color space by mashing up some of the features.
[5] According to the Stack Overflow user Tatarize, what Sarifuddin proposes as "HCL" is algorithmically similar to HSL.
While pointing out advantages in computational efficiency, they argue that Sarifuddin's work does not represent a significant improvement over the CIELAB color space while showing failure to reproduce the paper's claims.
