visibleTrigger="???????"

[Kusaywa]

Is there a "visibleTrigger" when stopped?
What I have below is 2 buttons.
A Play button that displays a "play" symbol when paused and a "pause" symbol when playing.
There is also a Stop button, which currently displays a light colored square when playing and a dark colored square when paused or stopped.
What I'm looking to do is, when paused it remains the light colored square, but when stopped displays the dark colored square.
THANKS
