Jermaine 说 it was gold, that was why they wore yellow ties on his memorial, and he was laid to rest in a 金牌 casket.
But I've also heard he liked yellow, red, black, green... And he must've, because most of his outfits were in those colors. Suppose he felt he couldn't wear 金牌 pants off stage! Lol!!! Would've been great if he had done that, though!
