This is “Crepuscule in Pink and Green – Valparaiso” by James McNeill Whistler. Painted in 1866, the oil on canvas captures a late‑afternoon sky over the Chilean port of Valparaiso. The scene shows British, American and French warships withdrawing as Spain announces its bombardment; the white hulls are partly illuminated by pink and green hues that Whistler used to convey twilight’s quiet glow.
Whistler himself sailed from London in March 1866 with the idea of fighting for Chile against Spain. He painted this picture while still in the port, and he left a few days later, riding into the hills on horseback after the Spanish ships launched their attack the following day. The painting is thought to record the moment when the foreign fleets were pulling out.
The composition contains a single visible flag – the French tricolour – perched above violet‑purple clouds that frame the horizon. Whistler’s brushwork suggests motion: sails billowing, waves rolling, as if the sea itself was breathing. Although he worked from memory and finished the canvas in one sitting, the overall effect is powerful; the colours blend into a soft, almost dreamlike evening light.
It was first shown at the French Gallery in London in 1867 and received praise for its magical rendering of motion and atmosphere. This work links Whistler’s interest in colour harmony with the dramatic naval events unfolding at Valparaiso during that spring of 1866.
