Caran d’Ache reveals art in its purest form with the Caran d’Ache + Klein Blue® collection, a celebration of one of the most remarkable artists of his generation. In an ode to freedom, Klein’s monumental works infuse the colour blue with a spiritual dimension, making the hue his own. Klein Blue® is the rich colour of the Mediterranean, the sky and the wide blue yonder. Defining his oeuvre is the International Klein Blue® - a highly saturated shade of ultramarine, revealed by the artist’s ingenious process, often considered the “the most perfect expression of blue”. The Caran d’Ache + Klein Blue® collection is a collaboration focusing on colour in its most authentic form, celebrating creativity for every use. This collection encapsulates the beauty of Klein Blue®, reinforced by the expertise of Caran d’Ache’s craftspeople that has been developed over an entire century.
