猩红色，柠檬色和深蓝色：1957年3月

This painting was made at Zennor, Cornwall. Heron has recalled that in the same month he 'painted the first of my other explicit vertical stripe paintings, the best known of which were those included in my exhibition at the Redfern Gallery in February, 1958. I painted other pictures in March, 1957, in which the colour was equally brilliant and flat, but in which the element of the vertical band or stripe was slightly modified'.
