My husband, Peter Jones, who has died aged 83, was a prolific artist of colour and light, best known for his Colourscape walk-in installations, each a series of interlinked chambers of translucent PVC, creating space with pure colour. He was also a mathematician and hang-glider pilot, and interested in science, meditation and spirituality.
Following studies in the early 1960s at St Martin’s School of Art in London – where he was influenced by the De Stijl movement – Peter made architectural constructions, which he termed Spaceplaces, within buildings and galleries, using coloured panels and rods. Working with his fellow artist Maurice Agis, he had shows at the Museum of Modern Art, Oxford, and at the Stedelijk, Amsterdam, and in 1967 they jointly won the Netherlands’ Sikkens prize for use of colour. They continued to collaborate until 1977.
