Violet No.11
"In a biting review for Le Charivari newspaper, Louis Leroy accused Monet’s Impression Sunrise, of not being a finished painting at all, but a mere preparatory sketch. Many more such criticisms were aimed at the fledgling movement over the following years, but one constant theme concerned their preoccupation with a single color: violet."
