Caran D'Ache Luminance 6901 Pencils Assorted Caran d'Ache Luminance 6901 Pencils are professional quality artists' coloured pencils. They combine the best light fastness with the smoothest permanent lead. Two years of research went into developing the formulation for Luminance 6901 in the greatest secrecy in the Geneva workshops. This work has been based on best pigments and the know-how guaranteeing the Swiss Made quality. In addition to the highest lightfastness, the Luminance 6901 leads benefit from an extreme softness which enables you to obtain subtle mixings and gradations, as well as blendings. Every shade has been formulated using finely-ground pigments chosen for their purity, intensity and resistance to UV.
