Chromatic Accelerator, 1967
acrylic on canvas
National Gallery of Canada (no. 15319)
© Claude Tousignant
This painting belongs to Claude Tousignant's third and most recognized series of circular works, "Chromatic Accelerators" (1967-69), in which he deployed various sequences of colour in even, concentric bands. As the viewer engages with these works over time, the rhythmic, chromatic juxtapositions generate a pulsating, optical experience, fulfilling Tousignant's goal to produce an object of pure sensation. Tousignant was intrigued by the circle as a structural form that has uniform peripheral tensions in which he could deploy colour in serial placement.
