Agnes Martin has described her paintings as being about “light, lightness, about merging, about formlessness". The horizontal lines of delicate colour with pencil outlines seen in this painting are typical of Martin's work. The bands were painted vertically to allow the paint to run down the length of the stripe, and the paintings were turned horizontally when finished. Although the painting is a metre and a half square, the artist used an eighteen inch ruler to draw the pencil lines, moving it across the width of the painting. This allows the artist's hand to be clearly seen, and on viewing the work closely, the irregularity of the pencil lines is evident.
