The Channel at Gravelines, Evening

The Channel at Gravelines, Evening (1890) captures the last light of evening over the flat northern French coast, one of four major paintings from Seurat's summer 1890 campaign at Gravelines. The evening light required careful calibration of the warm-to-cool colour shift from sunset sky to darkening water — a chromatic problem Seurat had also studied at Grandcamp and Honfleur. These Gravelines paintings were the final body of outdoor work he produced before his death in 1891. Museum of Modern Art, New York.

Warm orange and rose tones fill the sky while the water deepens towards cooler blues and blue-greens in the lower half. The transition from warm to cool is handled through methodical dot-by-dot gradation. The painted border of contrasting dots frames the composition within its own chromatic logic.
