Le Smokey Black Pon Takeover

Have y'all been getting the same outcome each time you use the coat randomizer? Like, I've purchased two recently, and used them each on a different TB, and they both turned out smokey black. Was this a coincidence, or a TB glitch, or maybe a randomizer glitch, or what? I don't really care; I like smokey blacks, but I was hoping for a different color the second time XD
