Illamasqua Cameo Nail Varnish ($14.00 for 0.50 fl. oz.) is described as a “cornflower blue.” (Sephora has it listed as “periwinkle blue.”) It’s a dusty, cornflower blue that leans noticeably purple. It almost more purple than blue, but it’s not true purple. Which, I suppose, tells you how complex and confusing this color family can be! I couldn’t think of a dupe–Essie Lapis of Luxury was too blue, while Essie Smooth sailing was too purple (and shimmery, too). I’d love to hear from you if you know of any dupe possibilities!
