At this point, Mitchell had been living in Vétheuil, a small French town along the Seine, for more than two decades. Surrounded by gardens, trees, and constantly shifting light, her daily experience of nature profoundly shaped her late work. Rather than depict the landscape directly, Mitchell translated her sensory and emotional responses into abstract form. In Untitled (1991), sweeping strokes of red, green, blue, orange, and purple surge across a largely white ground, capturing not a specific place but the lived sensation of movement, light, and atmosphere. The retained expanses of white lend the painting an airy openness, allowing the colors to hover, collide, and breathe, much like light filtering through changing weather.

In her final years, the boundary between abstraction and representation became increasingly porous. In Untitled, clusters of thick, muscular brushstrokes gather and disperse across the canvas, suggesting fleeting references to foliage, blossoms, or turbulent skies without ever settling into fixed imagery. The green strokes, in particular, seem animated—darting upward and outward, guiding the viewer’s eye across the surface with a rhythmic vitality.

The painting also reflects Mitchell’s deep engagement with the history of French modernism. Her vibrant color contrasts and energetic brushwork echoes Van Gogh’s emotional turbulence, Matisse’s chromatic daring, and Cézanne’s structural sensitivity to nature, yet these influences are fully absorbed into her own gestural language rooted in Abstract Expressionism.
