Since it was founded in 1720, "La Maison du Pastel" has never ceased counting among its clients some of the world's most renowned artists.
Degas, Chéret, Whistler, Sisley, and later on Bussy, Vuillard, Poliakoff and many others have, by their expectations, contributed to the elaboration of Roché Pastels, and have come to the shop to select colors known for their specific qualities :

- colours of an exceptional intensity and luminosity
- light resistant pigments
- an excellent adhesive quality to numerous supports
- a great surface coverage ability
- a unique texture

The English artist Paul Maze (1887 – 1979), explaining how Vuillard brought him to the store on Rue Rambuteau in the 1930’s to meet
Dr. Roché : « I was taken by God to meet God ! »
