Developed by chemists in partnership with artists, Winsor & Newton's Cadmium-Free Artists’ Oil Colours are formulated to match the vibrancy, opacity, lightfastness and permanence of traditional cadmium colours so you no longer need to compromise when seeking an alternative. With Winsor & Newton's 9 new highly saturated, bright, opaque colours, we've continued our cadmium-free innovation, opening up even more possibilities.
