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 I, LFI) under standard ASTM D-6901.

Every shade has been formulated using finely-ground pigments chosen for their purity, intensity and resistance to UV. The chromatic range Luminance 6901 is perfectly balanced and comes in sets of 16 (100% LFI), 38 (85% LFI) or 76 (80% LFI) colour pencils.
