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)
