When I am trying to switch colors around, I find it absolutely maddening that the currently selected color is not shown on the color picker. I’ve had to resort to making lists of what color it isn’t, so I can figure out by process of elimination what the current color name is. I suppose I could use the macOS Digital Color Meter application but please, include the currently-selected color on the color picker with a checkmark or something, so I can hover over it and find out its name. Or tell me I’m nuts and explain how I should be doing it instead—I’m not picky!
EDIT: in the clear light of morning, I realize what I really want. When I hover over the color of a label, I want a tooltip that tells me the color’s name, so I can select the same color for a different column’s label.
