Martin finished her first new set of paintings in 1974, showing them at Pace Gallery one year later. This room features selected works with pastel-coloured washes, testifying to Martin’s interest in variations of light colour. Artist Ann Wilson observed in 1974, ‘the colour in Agnes Martin’s work can be like the colour in rock at dawn, at noon, at sunset, depending upon where your perceptions are when you see.’

Martin rarely departed from variations of diluted red, white and blue paint, applied with a soft brush onto a surface covered in acrylic gesso. When examined closely, the fine graphite or coloured pencil lines that divide the colour fields are visible. She used a metal rule and masking tape to guide her hand in drawing her lines. Subtle irregularities in her pencil and the liquid pooling of the paint can be seen when the paintings are viewed from close by.
