If Aimé Maeght had not chosen, in December 1946, the title "Black is a Color" to open his first Parisian exhibition, that same title would have suited Vincent Proust’s show perfectly, for, like many artists he admires — Pierre Soulages, Louise Nevelson, Pierrette Bloch, Hans Hartung and many others — black is for him an inexhaustible source of inspiration and expression. The exhibition will therefore be called « BLACK » since this color plays the leading role there.     Vincent Proust brings black to life by sculpting it so that the eye gets lost in geometric repetitions. Under the mere action of light, black changes tone and intensity, sometimes even metamorphosing into white, its opposite. The hollow becomes relief, or vice versa, like printing forms. The exhibition brings together some twenty large- and medium-format works, many of which are made of cardboard and rendered in three dimensions, depending on the piece.
