what is the rarest colour of the psp

mine's purple.. i really like it since the slim and lite version of black is not very appealing.. i think they only issue the purple one in japan or mayb just initially.. anyway, it even has the option for watching tv and stuff, not just movies for the other version. but then again that is only applicable if you're in japan... and the manual's in japanese as well so i can't understand a thing.. it's okay, don't need manuals anyway, haha..

well the rarest one i can think of is the not the color but the crisis core special psp slim edition. i think they just realeased hundreds and mostly in japan. but for the color, haven't seen a red psp. i mostly see those black or piano black psp which is the most common.
