The pate cameleon or pate changeante was invented by the chemist Salvetat for the Universal Exhibition of 1863. It consisted of the creation of a paste which changed colour with a change in light. Thanks to vanadium oxide and Cerium oxide, the colour of the ground is grey under a natural light and mauve under artificial light. This technique of ground colouring was favoured for decorations with pate d'application also known as pate-sur pate.
