Adding HLC coordinates for the CIELAB color space
It’s really great that the Lab color space already is implemented in Buider! Unfortunately, the a* and b* coordinates are not that slick to use and their values are hard to imagine.
There also are the HLC coordinates, which are polar versions of the regular/cartesian Lab values. These coordinates would ease color selection and imagination, as they provide hue-lightness-chroma. You then could also pick matching colors easily, when you just alter the C value. Would be cool if those could also be implemented!
