This colour is really beautiful and unusual, as it is a duochrome. I would say the closest dupe would be MAC Club, except that Fervent is a loose pigment. The best way to apply this pigment is to mix it with Illamasqua Sealing Gel, or a similar product, in order to really bring out the glitter in it. As with all loose shadows apply it carefully to avoid fallout, but the Sealing Gel will really help with that. Overall I just think this colour is so special, and I love wearing it!
