If the white wire on a three-wire cable is painted red then it is probably a traveller. The three-wire cable would contain one hot condutor (black) and two travellers (red) and no neutrals. You would not be able to feed a second light off this cable. How many cables and how many wires are in each cable at the existing light and switch?
