In the mid to late 1960s, Margaret Worth made important contributions to the advancement of abstract art in Australia. Primarily known for her bold paintings of flowing bands of pure colour, Worth’s most challenging and rewarding gestures from this era are arguably her modular structures, such as this one. Painted a uniform blue on the outside and facing edge, and complemented by an orange interior, this deceptively simple painting device harnesses the traditional environment of an art gallery. Under lights, the work casts a warm orange blush on the ‘empty’ space of the supporting white wall, which is framed and enhanced by the cooler tone of the blue. A melding of colour and form, Untitled tests the boundaries of what painting can be.
