CIELAB Sliders

[matatk]

This might help in making suggestions, because it should make it easier to darken/lighten a colour until a solution is found.

Replace with (or add) CIELAB https://en.wikipedia.org/wiki/HSL_and_HSV#Disadvantages
See for implementation: https://github.com/THEjoezack/ColorMine/tree/master/ColorMine/ColorSpaces/Conversions

I agree. The RGB sliders are useless to improve an existing color pair. As a designer, I want to keep the "color" and improve with hue and/or saturation/vibrancy.

Thank you for the Pre-Release. Have tested the OS X native color dialogs and this helps a lot.

Yes, it does help.
Now I need to implement CIELAB.
