Lch

Lch is similar to it's cousin Cie-L*ab, except that it's been rearranged in the shape of a sphere which makes it useful for applications like high-end photo editing and retouching images. Read more about it here

Lab

Cie-L*ab is defined by lightness and the color-opponent dimensions a and b, which are based on the compressed Xyz color space coordinates. Lab is particularly notable for it's use in delta-e calculations. Read more about it here.
