California Tonalism was the West Coast flowering of Tonalism, the late-19th-century style of mood, atmosphere and restricted color associated with Whistler. In the cool, foggy light of northern California, painters like Charles Rollo Peters - whose moonlit Monterey landscapes are its emblem - and the Mexican-born Xavier Martinez developed an intimate, poetic landscape art of twilight, dusk and mist. Painted in harmonies of gray, violet and muted green rather than Impressionist brightness, these works prized reverie and suggestion over description. The mood persisted in California painting into the 1920s and 1930s before being overshadowed by the brighter Impressionist manner associated with the south of the state.
