Toni Harrower's work is beset with mathematical experiments in colour, composition, and scale. Within her systematic restraints and rules, the physicality of paint is allowed to gloriously resurface. Colours merge, layers build up, and Harrower's initial grid plans are both rescinded and accentuated. The passing of time becomes a creative form of its own – a process tangentially informed by her research into dementia and memory deterioration. In 2024, two paintings were included in the Visual Arts Scotland centenary exhibition at the Royal Scottish Academy, plus two in the Royal Academy Summer Exhibition.
