wikipedia- Seurat used a variety of means to suggest the baking heat of a summer’s day at the riverside. A hot haze softens the edges of the trees in the middle-distance and washes out colour from the bridges and factories in the background—the blue of the sky at the horizon is paled almost to whiteness. A shimmering appearance at the surface of Bathers at Asnières subtly reinforces this saturating heat and sunlight. Writing about these effects, the art historian Roger Fry reported his view that, “no one could render this enveloping with a more exquisitely tremulous sensibility, a more penetrating observation or more unfailing consistency, than Seurat”.
