A portrait of the German artist Heiner Thiel, wearing glasses and a beard, against a light-coloured background.

Heiner Thiel

The works of the artist from Wiesbaden, Germany, and curator Heiner Thiel offer the viewer an intense, highly nuanced perception of form and colour. His square or freely curved aluminium sheets, usually concave in shape and anodised in vibrant colours, create a fascinating optical interplay. As Thiel himself describes it: "Metal and colour in optical interplay create a virtual colour space that shines towards the viewer. It is almost impossible to escape the pull of light and colour, which guides their gaze into the depths of the surface."

Thiel's works consist of spherically curved aluminium panels that are anodised in a variety of colours. The free, sometimes biomorphic forms transcend the traditional picture size and expand the spatial impression into the virtual wall space. The spherical curvature creates flat, approximately 10 to 20 centimetres deep colour-spatial bodies, that - depending on the viewing distance and angle - allow constantly changing and fascinating colour and spatial perceptions, even under difficult lighting conditions. Additionally, the curvature and the outer contours of the panels cast shadows that change depending on the lighting situation. These dynamic shadow plays add another impressive spatial dimension to the works. Overall, an artwork is created that initially appears simple and clear in its appearance, but becomes extremely complex and differentiated upon further and more conscious perception by the viewer.
