Agostino Bonalumi's *Rosso* exemplifies his signature technique of "extroversion," in which the paper support is pushed and stretched from behind to create three-dimensional forms that emerge dramatically from the picture plane. A bold, uniform red acrylic surface flows seamlessly over the sculpted protrusions, transforming color into a tactile, spatial experience rather than a purely visual one. The work challenges the traditional boundary between painting and sculpture, inviting viewers to perceive light and shadow as active compositional elements across the undulating surface.
