The `color` return value would contain an array of 3 integers, with the values of the RGB channels. As you can see, there is no leakage of information on the application or content, and since the compositor is responsible for the user interaction, the application would never be able to call this method multiple times behind the user's back. You would need to talk to the GNOME Shell developers for implementing this functionality; you'd have to start by opening a bug: https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-shell Then, once it's available, you'd have to call it from GColor3. Alternatively, you'd have to talk to the Wayland developers and various compositor developers, and describe a Wayland protocol to achieve the same result.
