Her early work was figurative with a semi-impressionist style. Between 1958 and 1959 her work at the advertising agency showed her adoption of a style of painting based on the pointillist technique.[7] Around 1960 she began to develop her signature Op Art style consisting of black and white geometric patterns that explore the dynamism of sight and produce a disorienting effect on the eye.[6] In the summer of 1960 she toured Italy with mentor Maurice de Sausmarez, and the two visited the Venice Biennale with its large exhibition of Futurist works
