The Channel Sketchbook, Folio 12

A horizontal sweep of coral and rust across the center of the page, with paler pink above and soft gray-lavender below. The sky is brushed in loose, almost parallel strokes. A dark umber line sits just above the horizon — possibly a distant shore, possibly a bank of cloud. The paint is thin and the paper breathes through everywhere. Made around 1845, six years before Turner's death.
