From Vaccino's sense for color qualities, materiality and the balance of the line results the quality of his paintings. He has blended pure color zones together to form a moving field, with solid geometric segments - rectangles, squares, triangles and semicircles - positioned next to gestural painted sections. They lend stability to the picture and relativize the intensity of individual generous brushstrokes, as if they could question the system's order. In his interiors, Vaccino refers to the pastel shades and ornamentation of the painting of Matisse, luminous and sensual.
