From the 1960s onwards, Judd's works were made in factories using common industrial materials. Their simple forms allowed him to explore ideas of space, and to highlight the sensuous colour and distinctive surface of his materials. Each section of this work is bolted into a precise arrangement of colours and sizes. The colours were chosen from an industrial colour chart, and spray-painted on before the work was assembled.
