View of Collioure

Signac visited Collioure, the small Catalan fishing port near the Spanish border, during his extensive Mediterranean travels of the 1880s and 1890s, when he was systematically applying the chromoluminarist method he and Seurat had codified together. Unlike his mentor's more controlled technique, Signac rendered coastal scenes with mosaic-like dots of pure colour — cadmium oranges, viridian greens, and cobalt blues placed in rhythmic patterns to evoke the blaze of southern light. Collioure would later become famous as the site where Matisse and Derain launched Fauvism in 1905, partly inspired by the saturated colour vocabulary that Signac had already established there.

Signac applies strict Divisionist touches — small, separate strokes of complementary colour laid across the canvas in diagonal rhythms. The harbour water is built from greens and blues relieved by orange reflections, while the sky is rendered in warm and cool contrasts rather than flat wash.
