Created in the 1940's in collaboration with Picasso, these creamy, lipstick-like pastels are rich in pigment, cover well and have outstanding opacity. They may be thinned with turpentine, worked with a brush and can be applied to any surface. The 12-color set includes white, pale blue, lemon yellow, black, yellow ochre, burnt umber, cinnabar green yellow, green medium, mandarin, delft blue, permanent intense red and French ultramarine blue.
