Effets de soir
From The Art and Popular Culture Encyclopedia
Effets de soir (also called effets desoir or effets de soir et de matin) are the effects of light caused by the sunset, twilight, or darkness of the early evening or matins. They appear frequently in works by such painters as Vincent van Gogh Bernard Fries, Armand Guillaumin, and Camille Corot. Literally, it means "effects of evening" in French.
In 2008, the Museum of Modern Art curated a major exhibit of van Gogh's work of effets de soir.
