The Winter 2016 Collection from Essie is taking you back to the grooviest era — the swinging ‘60s. The set of six new shades include Ready to Boa, a bronzed mahogany; Party on a Platform, a garnet red; Oh Behave!, a minx peach frost; Getting Groovy, a metallic gold; Satin Sister, an ebony peacock blue; and Go with the Flowy, a cloudlike dove gray.
