"Modern art," said Matisse, "spreads joy around it by its color, which calms us." In this radiant painting he saturates a room—his own studio—with red. Art and decorative objects are painted solidly, but furniture and architecture are linear diagrams, silhouetted by "gaps" in the red surface. These gaps reveal earlier layers of yellow and blue paint beneath the red; Matisse changed the colors until they felt right to him. (The studio was actually white.)
The studio is an important place for any artist, and this one Matisse had built for himself, encouraged by new patronage in 1909. He shows in it a carefully arranged exhibition of his own works. Angled lines suggest depth, and the blue-green light of the window intensifies the sense of interior space, but the expanse of red flattens the image. Matisse heightens this effect by, for example, omitting the vertical line of the corner of the room.
The entire composition is clustered around the enigmatic axis of the grandfather clock, a flat rectangle whose face has no hands. Time is suspended in this magical space. On the foreground table, an open box of crayons, perhaps a symbolic stand-in for the artist, invites us into the room. But the studio itself, defined by ethereal lines and subtle spatial discontinuities, remains Matisse's private universe.
