Discrimination between positive and negative poles: Some varactor diodes have a black mark on one end, which is the negative pole, and the other end is the positive pole. Some varactor diodes have yellow and red rings painted on both ends of their casing, with one end of the red ring being the positive electrode and the other end of the yellow ring being the negative electrode
