In keeping with their contemporary policy of presenting existing and new products, Caran d’Ache www.carandache.ch collaborates always in close harmony with contemporary artists who use their product range in their work.

In 1992 Caran d’Ache engaged Sonja Burger to promote the color series „Supracolor“. A 4-page colour pamphlet of Supracolor with an owl study by Sonja Burger, reached international acclaim. In 1993 Caran d’Ache made a short documentary film with Sonja Burger drawing a orchid study structure to promote the „Prismalo“ series. The high acclaim of these short films in school art departments etc, led to further short documentaries, one notably, in the tropical gardens of Geneva dedicated to tropical plants, utilizing the newly launched color series „Prismalo“

In 2010 Caran d’Ache laboratories released the new series „Luminance 6901“ and additionally promoted a color pamphlet dedicated to Sonja Burger in demonstrating their art products, whereby pumkin studies in Autumn mood could be seen.
