I'm obsessed with the complexity of these two metallic nail polishes. I could stare at them for hours, watching all the subtle shimmery color changes. Both are iridescent and reflect a gorgeous variety of shades.
Orly Space Cadet ($10) looks exactly like it sounds: futuristic, bold, the nail polish equivalent of "Major Tom" by the Shiny Toy Guns. In bright light it reflects fuchsia, bright gold, and deep green from different angles. In low light the color is more violet.
Sephora by OPI in Mash-Up ($9.50) is from the new Glee collection and is Space Cadet's lighter counterpart. I don't watch Glee, but I secretly kind of enjoy their mash up songs, especially this one. Mash-Up reflects silver, hot pink, mint green, and even faintly gold toward the edges.
Photographing the complex iridescence of these colors was pretty difficult, but you can see it a little better in the pictures of the individual polish bottles. Sephora's website describes Mash-Up as "opalescent grey", but it's SO much more than that. Space Cadet is, too. Which one would you wear most?
