Provided is a non-stick coating including at least one functional decorative layer, including a pigment composition having a reversible variation of optical and/or colorimetric properties when the coating is subjected to a temperature variation between a cold temperature of 0&#xb0; C. to 40&#xb0; C. and a hot temperature of 80&#xb0; C. to 400&#xb0; C. The pigment composition includes at least one compound of formula YMFeQOin the form of particles, in which M is selected from the lanthanides, alkaline metals, alkaline-earth metals and metalloids with a degree of oxidation (DO) +3; Q is selected from the group made up of the lanthanides, non-metals with degree of oxidation +4, metals with DO +3 or +4, transition metals with DO +2 or +4, alkaline-earth metals and alkaline metals; and wherein x is between 0 and 0.3 and y is between 0 and 3.
