Toon Verhoef’s monumental yellow and blue painting Zonder titel evokes associations of a dream landscape, where semi-circular shapes float, vibrate and collide. If you take a long look at it, the competition between colour and form imposes itself on you. Verhoef’s work appears to revolve around the painting process itself. Paint is added and removed again, time after time. His use of brush, palette knife, scraper and sandpaper is testimony to his preoccupation with the material qualities of the painting. But this is not the only thing influencing the artist. In his work, he operates between the instinctive and a more formal approach to the medium of painting.
