Caran d'Ache Luminance - colour pencil

Caran d'Ache discovers the secret of light-loving colours and invents…
Luminance 6901
Caran d'Ache, Maison de Haute Ecriture, is once more emphasising its expertise in colour by offering professionals the Luminance 6901 colour pencil, a combination of the highest lightfastness and the smoothness of a permanent lead. Two years of research went into developping the formulation in the greatest secrecy in the Geneva workshops.
Certified lightfastness
At the request of the Colored Pencil Society of America (CPSA), the American Society for Testing and Material has developed standard ASTM D-6901 to determine the lightfast level of a colour pencil. With Luminance 6901, Caran d'Ache is the only brand to offer a set of 76 colours with 61 colours classified in the best category (lightfastness 1) under standard ASTM D-6901. Every shade has been formulated using finely-ground pigments chosen for their purity, intensity and resistance to UV.
Thought and produced in the respect of the environment.
Cut from California cedar, the Luminance 6901 colour pencils carry the FSC label, a guarantee of logging that is environmentally friendly and socially and economically endurable. Caran d'Ache is a rarity among world pencil manufacturers, for that it has obtained this label for both the type of wood used and its conversion in its Geneva workshops.
