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.

Cmyk

Cmyk is similar to the Cmy color space, with the addition of black (k). In theory the black component is not necessary, however this color space is primarily used in color printing where the mixture of cyan, magenta, and yellow result in a brown color rather than black.

We'll be adding support for ICC profiles to this page soon, but it's already available on our color converter page.
