I'm trying to make a function with a parameter so whenever I call it, it will change the button's back color but my code doesn't work, any ideas

Button button = new Button();
        private void Change(object sender)
        {
            if (button.Visible == true)
            {
                button.BackColor = Color.Red;
            }
        }
        private void hr1_left2_btn_MouseEnter(object sender, EventArgs e)
        {
            Change(hr1_left2_btn);
           
        }

Perhaps like this? I've changed the Sender Arg type of the Change function to ref a button object.

        private void Change(Button sender) {
            if (sender.Visible)
                sender.BackColor = Color.Red;
        }

        private void hr1_left2_btn_MouseEnter(object sender, EventArgs e) {
            Change(hr1_left2_btn);
        }
