Yes, the issue is that the colorpicker button in the global color-picker has kind of a three state.

• Left-click : point colorpicker
• Right-click : area colorpicker

And so to disable it one need to either Left-click if point color picker selected otherwise Right-click. This is really annoying.

Describe the solution you'd like

• Left-click : point colorpicker

• Right-click : area colorpicker

• Left-click / Right-click again would disable the picker

The question is now how to switch between point / area color picker ?

My proposal would be a Ctrl+click on the canvas would switch the mode from point / area.

EDIT:
Not sure about this last point and also all pickers are using the same UX. More thinking is needed here.
