The Arundel series of paintings, begun in 1973,[11] features barely visible graphite lines and accumulations of white paint on white surfaces.[4] In the custard-color Ice Blink (1989), a tiny sliver of red at the bottom of the painting is enough to set up perspectival depth, as is a single bar of purple at the bottom of the otherwise sky-blue Memory (1981).[13] Begun around 2001, the Piths, canvases with deliberately frayed edges and covered in thick black strokes of paint, indicate Truitt’s interest in forms that blur the lines between two and three dimensions.[4]
