I tried both polarity, and only the Red lights up at all. All 5 are the same.

Q: I put 3.3v on the common pin, and ground on each R, B, G. Only the red lights up, on all 5 modules. Is there a trick to using these?

OzTm Being "for Arduino", I would assume that these modules are made to work when supplied with 5V, not 3.3V. The red LEDs usually require a little less voltage than other colours to light up, so that's why yours is working.
