When I use the pick color tool it works well but I have not found a way for the mouse/pen hover to display the color numbers as well as the color sample.
Would be nice and helpful. Also sgould be user choice to display RGB or HSL, or HSV, or Lab.
I have a PC work around: use windows power toys color picker..it overlays with the R7pro picker and displays my Lab numbers. And Power Toys has a handy zoom to carefully pick desired color...would be nice 
to have in R7.
One account,
many possibilities
