How would you wait until a humanoid dies and finishes respawning?

I have a simple coloring system that changes the player's color once they respawn. However, I'd need to wait until they finish respawning and then apply the colors, else they'll revert to normal.

I've already tried this, however it doesnt seem to be working (line 4);

repeat wait() until char.Humanoid.Health == 100

Here's my full script;

game.Players.PlayerAdded:Connect(function(plr)
	local char = plr.Character or plr.CharacterAdded:Wait()
	char.Humanoid.Died:Connect(function()
		repeat wait() until char.Humanoid.Health == 100
		local onecolor1 = char.Wing1
		local onecolor2 = char.Wing2
		-- wing colors above
		local twocolor1 = char.Body
		local twocolor2 = char.Antenna1
		local twocolor3 = char.Antenna2
		-- body colors above
		local randomcolor1 = BrickColor.Random()
		
		onecolor1.BrickColor = randomcolor1
		onecolor2.BrickColor = randomcolor1
		-- coloring the wings
		local randomcolor2 = BrickColor.Random()
		
		twocolor1.BrickColor = randomcolor2
		twocolor2.BrickColor = randomcolor2
		twocolor3.BrickColor = randomcolor2
		-- coloring the body
	end)
end)
