Colour operates as both structure and sensation within the work. Applied instinctively yet with increasing control, it shifts between areas of density and openness, guiding the rhythm of the composition while resisting fixed meaning. Walker often embraces dissonant or unexpected palettes, using colour to disrupt form and to open new spatial and emotional possibilities within the painting.

At the core of Walker’s practice is an engagement with uncertainty. Her paintings are not pre-determined but evolve through risk, chance and physical intervention, allowing the medium to assert its own agency. Figures and forms appear and dissolve, giving rise to compositions that feel at once immediate and unresolved. In this way, each work becomes a record of its own making, holding traces of gesture, revision and instinct.

Walker’s paintings function as psychological terrains, shaped by memory, sensation and internal states. Balancing control with spontaneity, her work invites a sustained looking, where meaning remains open and continually shifting.
