A dynamic abstract composition by Sam Francis, 'Trietto III' features overlapping shapes and gestural marks in a vibrant palette of blues, reds, and greens. The painting showcases Francis's signature style of controlled chaos and spontaneous expression.

Sam Francis (1923-1994) was an American painter and printmaker associated with Abstract Expressionism. He is particularly known for his large-scale, colourful abstract paintings. Francis spent time in Paris, where he was influenced by both American Abstract Expressionism and French modernism. His work often features drips, splashes, and washes of colour, creating dynamic and energetic compositions. He explored the use of colour and light, often leaving areas of the canvas bare to allow the colours to breathe. 'Trietto III' exemplifies Francis's style, with its interplay of translucent forms and bold, gestural marks. The composition is built from overlapping shapes in hues of blue, red, and green, punctuated by splatters and drips of paint. A grid-like structure in black provides a contrasting element, adding a sense of depth and complexity to the composition. The overall effect is one of spontaneity and controlled chaos, characteristic of Abstract Expressionist aesthetics.
