I'm going to use the prolight RBG led from a joe jedi saber in a pvc saber. I want to make it purple but I don't know to drive it.

I'll be useing 2AAA battery pack for 3V. The leds Forward voltages are

Red 2.30 max 3.10

Green 3.40 max 4

Blue 3.40 max 4

What's the best way to drive it direct, mico puck, resistor?
