I don't think it would matter if Elvis disliked a colour or not.... he would only wear some jumpsuits only a few times e.g.
Black Fireworks - 3 times
Black Conqistador - 2 times
Saturn Suit - 1 time
Royal Blue Fireworks - 2 times
So to only have worn the Red Pinwheel Jumpsuit 5 times is more than some others.
