O P A L  a r t i s t  g r o u p


The artist group OPAL was formed in 2011 on the basis of a long-standing
collaboration between Johannes Keller and Hans-Christian Neumann.
Together with Daniel Reimer, they founded an artist group to work on concrete and
constructivist art in painting and sculpture.
Their basic format is the square. The artworks – paintings, reliefs and sculptures – are
developed in a collaborative process. Thus, each piece has three authors.
As a special feature, they developed series consisting of multilayered panels.
Viewers are invited to discover the continually changing systems within these series.
The name OPAL is based on a quote from Lessing’s „Nathan the Wise”:


„The stone was an opal, which shed a hundred lovely colours...”
