Hello devs,

I have succesfully reached a considerable milestone in modifying the current colorwheel in my branch. It now looks like this:


I need to add a 'Lightness' value bar similar to the Alpha bar in the wheel GUI. 
I am having trouble finding the code that does that ! Been stuck on it for a day, can't afford to lose more time on this. Can anyone help ?
