When I first got my bottle, I immediately contacted Orly customer service and told them they had sent me the wrong color because it looks like blue grey. I even filed this under grey nail polish. Orly e-mailed me back that its the right color. I sat on this for almost a week and then went outside and held the bottle to the sun and said “They are right! I was wrong, it is plum.” In the sun, it looks like a very deep aubergine. I honestly didn’t know what I was looking at. This color is an enigma because it looks like other things than what it really is. This is a really cool plum and looks closest to nebula. Figuring out how to do an ombre with Plum Noir, Secret Heir, and Indigo Skies. This is so dark and emo vampy I love it.
