Colour-changing nail polishes are a must-have this year. A little while ago we posted about China Glaze’s color-changing Tranzitions collection and now we’ve stumbled across the new Shade Shifter from Orly.

The Orly Shade Shifter Gel FX changes colour according to temperature; it’s dark when you’re cold and clear when you’re hot, and wearers can watch as the shade of their nail polish changes according to their body temperature.

Shade Shifter is added after your chosen nail colour, but not in place of the top coat.
