A striking example of Bonalumi's signature *Pittura-Oggetto* approach, *Azzurro* features a monochromatic expanse of deep blue vinyl tempera stretched over a shaped canvas, its surface pushed and pulled from behind to create subtle three-dimensional protrusions. The work dissolves the boundary between painting and sculpture, transforming color into a tactile, breathing presence that shifts with changing light and perspective. Bonalumi's restrained yet dynamic manipulation of form invites the viewer to perceive the canvas not as a flat support, but as a living, spatial object.
