The 88 ninja was probably intended to be Heroic (he's fighting a Snake Man, though with MotU having multiple evil factions that's not conclusive) and white was a good guess by the people who had to come up with colorways for Classics, since Ninjor was traditional black. I would guess white ninja costumes had the second-highest profile in 1988, if only due to GI Joe's Storm Shadow.
