There is now a `on_color_changed` callback that clients can optionally hook into to receive real-time updates while the user is picking a color. If the user hits Cancel, the callback gets called once more with the color passed in while constructing `ColorPicker`. If the user hits OK, the same happens with the currently selected color instead. Programs therefore can perform all their updates with this callback, and only care about `ExecResult` if they want to make a decision, like if we should write the result to `ConfigServer`, for example.
