Emile Claus, Woman at a Sunlit Doorway — Postcard

The wall is the real subject: a whitewashed stucco facade blazing with pink, cream, lavender, and warm-orange light, built from countless short comma-strokes in Emile Claus's most pointillist manner. A turquoise-green window frame and matching door anchor the composition, and in front of it all a Flemish woman in a white linen bonnet and blue apron-dress pauses near the entrance, a green pail in hand.

A striking choice if you're drawn to the technique itself rather than the story it tells.
