How do you change a players skin color?

I created a script and put it in the server script service to change a players skin color when they join the game. There are no errors but it doesn't do anything.

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		if character.Humanoid.RigType == Enum.HumanoidRigType.R15 then 
			character.Head.BrickColor = BrickColor.new("Royal purple")`
			character.UpperTorso.BrickColor = BrickColor.new("Royal purple")
			character.LowerTorso.BrickColor = BrickColor.new("Royal purple")
			character.LeftUpperArm.BrickColor = BrickColor.new("Royal purple")
			character.LeftLowerArm.BrickColor = BrickColor.new("Royal purple")
			character.RightUpperArm.BrickColor = BrickColor.new("Royal purple")
			character.RightLowerArm.BrickColor = BrickColor.new("Royal purple")
			character.LeftUpperLeg.BrickColor = BrickColor.new("Royal purple")
			character.LeftLowerLeg.BrickColor = BrickColor.new("Royal purple")
			character.RightUpperLeg.BrickColor = BrickColor.new("Royal purple")
			character.RightLowerLeg.BrickColor = BrickColor.new("Royal purple")
    			character.LeftHand.BrickColor = BrickColor.new("Royal purple")
    			character.RightHand.BrickColor = BrickColor.new("Royal purple")
    			character.LeftFoot.BrickColor = BrickColor.new("Royal purple")
    			character.RightFoot.BrickColor = BrickColor.new("Royal purple")
		end
		if character.Humanoid.RigType == Enum.HumanoidRigType.R6 then
			character.Head.BrickColor = BrickColor.new("Royal purple")
			character.Torso.BrickColor = BrickColor.new("Royal purple")
			character.RightArm.BrickColor = BrickColor.new("Royal purple")
			character.LeftArm.BrickColor = BrickColor.new("Royal purple")
			character.RightLeg.BrickColor = BrickColor.new("Royal purple")
			character.LeftLeg.BrickColor = BrickColor.new("Royal purple")
		end
	end)
end)
