Illamasqua Radium is green. Electric, grass green. Temptalia describes it: chartreuse green with yellow undertones and iridescent green and chartreuse micro-shimmer. Gorgeous application, two coats, the shimmer adds that extra oooomph to my favorite nail color for spring. Accent is Utopias Hibiscus, the perfect blend of matte red, orange white green and tiny holographic assorted glitters. I've worn similar combinations before and am sure I will again.
