"Where There is No Vision, the People Parrish"

From American Heritage (click to enlarge)

Maxfield Parrish (1870-1966) was already a familiar magazine and advertising illustrator when he created this promotion for Edison Mazda light bulbs in 1922. As a child gazes at the lamplight’s reflection in the water, a couple stares at its source atop a pile in a mystical Venetian harbor. Behind them is a sky of the cobalt that was known as Parrish blue. Parrish achieved the luminous colors that marked much of his artwork by a technique involving several coats of oil and varnish.

The only piece I have by Parrish is an advertising booklet for Jell-O. It's beautiful but nothing like this advert.

I want to wake in a room whose walls are Parrish blue.
