Currently, anythingmany areas in a Plasma Wayland session that attempts to do colour picking under Wayland is dysfunctionaldon't use the KWin API, because they haven't been made to support it. I'm not sure if it would be better to expoPorting KDE things that don't use this via D-BUS like screenshots areAPI to use it (or an equivalent, or to create a standardised Wayland protocol as "request pick" and "colour picked" lend themselves very well to how Wayland protocols worksuch as the screenshot portal's PickColor method) should be done.
