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.

Yxy

The Yxy color space expresses the Xyz color space in a different way, in terms of only x and y coordinates which allows for a 2d representation.
