Vibration, movement, rhythm, light and the absence of it are some of the topics that surrounds If the Eyes Were not Sun-Like… The title is a reference to a quote by Johann Wolfgang Von Goethe. The Theory of Colours by Goethe has an important influence on Heinz Mack’s oeuvre. Pieces as Ohne Titel (Klassische Chromatik) (2001) are the proof of the artist’s interest in this scientific approach to colour. The artist use the colours that conforms the phenomena of rainbow to compose these chromatic pieces. As becomes evident in Untitled (1958), white is always present as the base for light to bright: “Alongside all the ‘colors of light’, I need white as the canvas, as the background, as a reflective area for light. Therefore, white always plays a crucial role in the purity and brightness of the colors…Here color becomes an emanation of light, which occurs as both part of the spectrum and as the spectrum. This emanation effects the appearance of the color, which is itself emanating from the canvas and which fills the room”.
