This is a very rich pigment and it goes on so opaque and rich over a primer. Needless to say, a little goes a very long way. As with most pigments, I would suggest doing your eye make-up before foundation or concealer as you can experience fall-out, minimal fall out in this case, but still.
Overall, this is a pigment I need to wear more, because it's stunning. It takes some patience and time to apply and work with it but the end result is so worth it. It's a unique shade and one of my best performing pigments. In my stash the only similar shade I have is Urban Decay's Lounge eyeshadow, which I believe is discontinued in pan form. Lounge has a similar base, but less blue duo-chrome and is much more bendable and buttery but less intense in colour pay-off.
