Temporarily disable selection handles while changing color
When I'm changing an object's color, its selection outline and other debris like "live corner" markers get in the way of previewing the color change.
I usually have to deselect the object to see if the change "worked" with the rest of my design. It's a tedious workflow.
Illustrator should temporarily turn off these markers while I'm changing the color.
Every other drawing app does this.

When I need to pick a color like you do, I disable edges — Ctrl+H.
Still, what you propose is handy.
