Patrick held his first solo show in 1961 at the Portal Gallery, London. It was the first one-man show by a Pop Artist, though they were not even called that then. A few years later, Hughes made two seminal reverse perspective works, Infinity and Sticking-out Room. In the 1970s Hughes’ name became synonymous with rainbow paintings, which also became very popular as prints and as postcards; people enjoyed them as decoration, but for Hughes the rainbow represented a solid experience.
In the late 1980s Hughes revisited exploiting the difference between perspective and reverspective and solidifying space. For the last 25 years his 3-D reverspective paintings have been in demand, exhibited around the world and featured in many public collections. The experience of seeing a Patrick Hughes sculptured painting, in reality, is really to experience unreality and the paradox of illusory space and movement.
