The Belgian artist Raoul De Keyser (1930-2012) didn’t start painting seriously until he was in his mid-30s, and when he did, it was with a light hand. The broad selection of paintings in “Raoul De Keyser: Touch Game,” which covers most of his career, includes many sparing arrangements of delicate marks that look like high-concept game boards. Some divide blocks of green with white lines, like soccer fields; others evoke views through microscopes, or high-speed photographs of physics experiments. A cloud of blushy marks, in “Front” (1992), looks like a vigorously erased test paper.
What it all has in common is that it’s technical without being inaccessible. You don’t need any expertise in color or paint application to appreciate that De Keyser was doing something small scale, elegant and specific to his medium.
