Mac dock icon color reverts to default when app closed

I changed the dock icon color to yellow, which displays properly when the app is open. When I close the app, the icon reverts to white.

Is there another setting I'm missing?


Thanks for the feedback. On Mac, app icons get reverted as you quit the app. I recommend keeping the app opened but if you want to change it completely, check below post. It'll revert back if you update though. Thanks!
