Tonal Impressionism is a style of "mood" painting that keeps Tonalism's simplified compositions and limited palette while borrowing Impressionism's brighter, more chromatic color. The term was coined by art historian Harry Muir Kurtzworth for an exhibition he curated at the Los Angeles Art Association Gallery in the Los Angeles Central Library in June 1937, where prominent California painters showed moonlights, dawn and dusk scenes, and quietly lit interiors rendered in blue and violet tones rather than the earth pigments of traditional California Tonalism. The idea was to work in low-light conditions - studio lamplight, moonrise, sunset - with the full chromatic range of Impressionism. More recently the name has been reused for a method of massing in tonal values without underdrawing.
