Unlike traditional acrylics, all 75 of the Atelier “Interactive” paint colours do not suddenly form a skin when drying. Atelier Interactive paints change the painting process from that of traditional acrylics, as they give the artist plenty of time to blend and re-work. They are easily ragged off to blend or reveal layers, as the paint when re-wet is re-workable.The patent-pending formulation allows even touch-dry paint to be re-worked or ragged without a plastic look or feel and minimal colour shift. The intense paint colours will dry to a satin-like finish. Atelier Interactive paints are an artist quality paint that is archival and lightfast.
