MAC Vanilla is a silvery pearlescent highlight with a copper duochrome. Again, it is so stunning, probably one of the prettiest highlights I've ever seen. Copper Aura and Moon Glow are similar, especially when it comes to the copper sheen.

Sidenote, can I add to this that Copper Aura stays on my face the ENTIRE frickin' day? No fading with this baby! Holy cow.
Conclusion? If you're looking for a cheaper option for the Vanilla pigment, go with Pure Luxe Copper Aura eyeshadow. Sure, it runs slightly more pinkish, but on the face the difference simply is neglectable. I'd say they are a 90% dupe. So save yourself some moneyz! If you wished Vanilla would be slightly more golden-albatross-ish, you could try Moon Glow. They are both amazing and honestly, I haven't touched my MAC sample since I got them.
