Heron commented in 'A Note on my Painting: 1962' written to accompany his 1963 exhibition at the Lienhard Gallery, Zurich, 'For a very long time, now, I have realised that my over-riding interest is colour. Colour is both the subject and the means; the form and the content; the image and the meaning, in my painting to-day ... It is obvious that colour is now the only direction in which painting can travel. Painting has still a continent to explore, in the direction of colour (and in no other direction) ... it seems obvious to me that we are still only at the beginning of our discovery and enjoyment of the superbly exciting facts of the world of colour. One reels at the colour possibilities now: the varied and contrasting intensities, opacities, transparencies; the seeming density and weight, warmth, coolness, vibrancy; or the superbly inert 'dull' colours' (see V. Knight (ed.), Patrick Heron, London, 1988, p. 34).
