From the year 1973, Marcelle Ferron made a return to painting, without however leaving stained-glass. Moreover, in 1975, she created the one for the Amos courthouse in Quebec. That same year, she exhibited at the Equinox Gallery in Vancouver and at the Les Multiples gallery in Quebec City, among others.

The untitled work from 1975 is characteristic of this period. Light, vibrant and metallic colours appear little by little in Ferron's work. With a renewed colour palette, the artist retains all of his ample and free gestures. Calligraphic black strokes are also appearing, reminiscent of Asian traditions. She managed to create in the works of this decade a whole new light and radiance inspired by her glass achievements.
