This chart was inspired by Monet's painting of the same name. Oscar Claude Monet 1840 - 1926, was a founder of French impressionist painting, and the most consistent and prolific practitioner of the movement's philosophy of expressing one's perceptions before nature, especially as applied to plein-air landscape painting. The term Impressionism is derived from the title of his painting Impression, Sunrise (Impression, soleil levant). Painting outdoors, he broke the tradition of portraying a subject literally by conveying the fleeting effects of atmosphere, time of day, and season upon colour and light. Eliminating black and grey from his palette, he represented natural colour like a prism, breaking it down into its individual components, often painting a series of the exact same view under different light and weather conditions. Monet brought the study of the transient effects of natural light to its most refined expression, ultimately becoming a forerunner of 20th century modernism.
