Don't know how to add, name, and configure a control?
Name the default Screen control Source, add another Screen control, and name it Target.
Set the Fill property of Target to this formula:
If("Red" in ScreenFills.Selected.Value, RGBA(255, 0, 0, 1), RGBA(54, 176, 75, 1))
Target appears in the color that you chose.
On Target, click or tap the Shape control to return to Source.
To return to the default workspace, press Esc.
