Try this. This relies on the fact that Red and Blue LEDs do not have the same forward voltage. Since I can't remember which has the higher forward drop, you will have to try it both ways.
Throw that switch away and buy a spdt(single pole double throw)switch and wire it as my schematic shows....its no good me giving you a schematic for using that switch you have because there is no need to make things complicated.... get a single pole double throw switch, two 470 ohm resistors ,your two leds and the schematic is uploaded for you .....do try not to be too scared.......

heres the schematic again with the switch shown operated in both possible positions with the respectve leds shown that will be on(or off).....do not be scared of it.....thats one way to use his existing switch i suppose but look at all the extra parts invoved ...im sure as long as bazbalz sees the leds light up when he operates his brand new spdt(single pole double throw)switch thats all that matters -let ther be lightssssssssssssssssssssssssssss
dont be scared of the spdt switch!!!!
