There's not really any such thing. One common and therefore cheap type of laser diode emits a red light, as does the fairly common (or at least it used to be common; the diodes are so much cheaper I imagine they mostly use them now) laboratory helium-neon laser. So if I had to pick a single color that was "common" I'd say red. There are green and even blue laser diodes now, but they're more expensive than the red ones and therefore aren't as ubiquitous.
