Featuring selections from the Dalhousie Art Gallery Permanent Collection, Wavelengths explores how artists engage colour not merely as pigment, but as a language of affect, perception, and resistance. Featuring artists such as Rita Letendre, Claude Tousignant, Garry Neill Kennedy, Gerald Ferguson, and Michael Fernandes, the exhibition traces Canada’s contributions to abstraction and conceptual art while also positioning them within international dialogues. From radiant colour fields to conceptually driven structures, the exhibition considers how colour operates as rhythm, signal, mood, and encoded meaning.
