Instead of being built up through an accumulation of brush-strokes which eventually fill the canvas, this painting is made through a process of removal. Innes has erased paint with turpentine to create forms which are strictly geometrical. By using simple shapes, Innes focuses attention on the qualities of the paint itself and highlights subtle variations in colour and tone. By taking away paint rather than putting it on and by revealing the various coloured residues of the paint, Innes allows the viewer to participate in the creative process itself.
