The paint is known by all those names, and probably many others.
Most of the spray-painters I know though will refer to it is a pearl paint. The "pearl" is the tint thing they stick in the paint to give it a different colour in different light.
Thus, a single pearl paint will (I think) usually flick between two base colours, but you can add multiple pearls if you want to get really trippy. A pearl (I think) can also be as simple as the really cool white paint I want for my frame, which is simply white, unless the light hits it at the right angle, usually along crease lines or the edge of tubes) where it will show off a coloured tint (I'm a big fan of blue).
I hope that makes sense. It's my understanding, but is really only a compilation of bits and pieces I've heard from people who do the stuff, so I don't know how much I've mis-interpretted.
