Schermuly’s mutable and original oeuvre led him out of an abstraction governed by visual rules and into the fascination of reality-inspired colour. The intensity of his gaze explored what the appearance of the world has to offer to a virtuoso colourist for a painting. He was interested not in recreation but in understanding the visible to develop colour phenomena suitable for painting. Profound knowledge of the history of the art of painting was for Schermuly a guarantee of his originality. The elaborately prepared and lavishly produced book presents an artist of rare distinction to the isms of the second half of the twentieth century.
