Bas Geerts' work is characterized by an openness of form, a kind of agility that manifests itself on several levels simultaneously.
In the first place, there is the play of colors. Bright hues enter into a synthesis and optically merge into new shades. Each color seems in motion and seems to want to assimilate with its complement.
Second, the painting itself seems to change according to the position the viewer takes in relation to the work. The reflection of the metal sheet will constantly change, while at a distance, the lines of the composition, still clearly distinguishable up close, merge into a continuous whole.
In addition to color, the openness of form is reflected in the way the composition of the paintings is created. Each design is generated by a computer program written by Geerts himself. In this way, Geerts is creator of a work of art that is, as it were, not created by himself: he executes what he had not foreseen.
