Classic Stagger/Shuffle Question for Brewmaster

I am an absolute nooblet so please bear with me.With Brewmaster, I understand that Purifying Brew cleanses the damage I've staved off with my passive.My question is: is there a visual cue for that incoming damage? I would like to get in the habit of optimizing when I pop that brew, but I have no idea how much incoming damage is happening, or when it's happening. I read something that says there's a green-yellow-red visual cue, but I've been unable to find anything like that on the screen.Apologize if this question doesn't make sense the way I explained it. Happy to take another crack at the wording if not.Thanks! via /r/wow https://ift.tt/OKUjJAE
