Since 1969 an important aspect of Bridget Riley's work has been its concern with the interplay between light and colour. Commenting on her use of stripes in this regard the artist told Robert Kudielka (op.cit) that she chose them because they are ‘unassertive forms’, unlike the shapes she was using previously (and which, in addition, often had distracting symbolic associations). ‘Form and colour seem to be fundamentally incompatible; they destroy each other... Colour energies need a virtually neutral vehicle if they are to develop uninhibited. The repeated stripe seems to meet these conditions’.

After 1969, the artist extended her original colour range of ‘pure’ red, green and blue on white into ‘mixed’ or indefinite scales of orange, green and violet or pink, lime-green and turquoise. She chose these latter colours because their capacity to ‘spread’ into the adjacent white bands was greatest. ‘Cantus Firmus’, in which sets of narrow pink, turquoise and lime green stripes alternate at carefully modulated intervals with bands of white, grey and black, introduced a new dimension of complexity. The spread of colour into the white areas is countered by the action both of the black bands, which intensify the colours next to them, and by the greys which get progressively darker towards the centre of the canvas. The effect is rhythmic and episodic, unlike the earlier ‘Early Morning’ (1967–8) (T.1032) where the very narrow parallel stripes produce a shimmering overall ‘curtain’ of colour in front of the canvas.
