Light is the decisive constant in the overall work of the artist Heinz Mack. The "Zero" years (1957-1963) were initially marked by a turning away from painting. In 1957, Mack decided against painting with colours and replaced them with the concept of structure - he titled his black and white paintings "Dynamsiche Strukturen" (Dynamic Structures). In 1963 Mack painted his last painting on canvas, having decided to abandon panel painting altogether. However, colour structures, which he had discovered in 1960 during light experiments, soon played a role in his artistic work again - from this time onwards, he occasionally created multi-coloured structural drawings, which Mack soon called “Farbchromatiken" (Colour Chromatics). The subject of the Colour Chromatics is the continuum of coloured light. The colours of light in the sense of the prism and its physical laws naturally play a decisive role. However, in the artistic realisation, Mack is much closer to the colour theory of Johann Wolfgang Goethe and the elementary experience of the rainbow, which is at the same time an elementary experience of light, than to Isaac Newton's colour physics. Mack's return to panel painting in 1991 was also based on the light experiences of the “Zero” years and colour is conditioned by light. In his “Chromatic Constellations" (Chromatische Konstellationen), which includes the present work “Später Sommer” ("Late Summer"), Mack understands "colour as light and light as colour" (Mack). Nuance, as a transition zone from one colour to another, plays a central role as a decisive principle of chromatics. The form and extension that the colour takes on the canvas serve a rhythmic constraint within which the light appears as colour. The surface on which the colour expands is the result of very differentiated and complex painterly constellations that include colour contrasts, complementary relationships, colour neighbourhoods and temperatures and, last but not least, colour intensity, which unfold their effects in the encounter with light.
