In a style that takes inspiration from the biomorphism instigated by Dalí, Picasso, and Miró, Kandinsky releases the languid little cursive forms from their geometric straitjacket, where he had inserted them in his earlier Bauhaus compositions. He transforms them into a playful ballet populated by motifs that are part animal, part fantasy, in a slow freefall. Bleu de Ciel is the painting of fantasy and poetry.
Kandinsky has reinvented himself: nature and life now take up the foreground. This desire for activity also comes across in his new way to deal with the surfaces. Like Picasso, Braque, and Masson, he blends pigments of color with sand to accentuate the contrasts between textures.
