In the 1960s, Huguette Arthur Bertrand’s painting became more lyrical. The straight streaks were replaced by softer black brushstrokes.
In the painting Raz de Marée (Tidal Wave), Huguette Arthur Bertrand’s gesture divides the composition while shape and background start to merge. Huguette Arthur Bertrand no longer used only the contrast between the background white and the form’s colour, but started to superimpose large black brushes and flat areas of colour. In this painting, we can already imagine that colour was about to invade the entire surface of the canvas.
