L'invention concerne un procédé de dépôt d'un revêtement sur un substrat (100), ledit procédé étant caractérisé en ce qu'il comporte une étape de dépôt d'une couche mince intermétallique (110) sur ledit substrat (100), de sorte à obtenir, à l'issue de cette étape, une pièce d'habillage (10) présentant une couleur finale prédéterminée. A method for depositing a coating on a substrate (100), including a step of depositing a thin intermetallic layer (110) on the substrate (100), so as to obtain, at the end of this step, an external part (10) having a predetermined final colour.
