At first I was like, hmmm white??? But it TOTALLY makes sense considering a white background/primer (even nailpolish) brings out the true color of the color placed on top of it. The consistency is similar to that of other eye primers, a bit thicker than the Smashbox eye primer (similar to the consistency of the MAC Studio Fix Concealer), but easy to apply. If anything I like eyeshadow primers that are a tad bit thicker because I feel like they hold onto the eyeshadow more. This white primer definitely brightens up eyeshadow colors and gives the appearance of being really pigmented. I haven't had a chance to do a complete look with it yet, so I don't know how it will hold up in terms of staying power (if it will crease or not), but so far just playing around with it, it looks promising. I will definitely keep you ladies posted and try to do a look using it this week.
Below is a comparison pic of a random eyeshadow color by itself, on top of the Smashbox Primer, and on top of the NYX Eyeshadow Base in White.
