The series, ‘Chroma Shape’ and 'Light Shift' reference both Modernist geometric abstraction and the spatial language of landscape. The perception of colour and space is informed by atmospheric light shifts, and virtual screen gradients, seen in contrast to hard edged shapes, which play with the push and pull of the picture plane. Distant horizons suggest optical depth, form and ground. This spatial tension within the picture plane makes reference to framing devices such as Renaissance tondo formats, tromp l’oeil and Modernist framing and compositional conventions. The colour conversation within these works is informed by several colour references; signatures observed within nature; atmospheric light; colour theory and formal abstraction, particularly influenced by the colour field painters, The Supremacist and geometric construction.
