Varnish your nails yellow and don't like the colour anymore? Hold your nails in hot water and the yellow colour turns orange! Again in the mood for yellow? Hold your nails in cold water and the nailpolish returns to the first colour.
This nailpolish is also very handy to get ombre nails. Hold the top of your nail in hot water and you get that dip-dye effect on your nails without messing up.
