i was at the paint shop today and inquired about the 432 blue just to see how many variants there are. its called monaco blue on the color chips but methnyl blue in the big book but its the same paint, but i did find out that in the variants there is 2 of them that can have a pearl effect through them, one's got a purple pearl effect and i'm pretty sure the other was a mint effect.( think the pearl effects are a later year thou)
Guess you better trust who's painting your car to make sure they get a good match.
