Last week I repaired and repainted the walls in our first floor sitting room. The main wall is lit with a raking southern light and this caused the sandy, grooved texture to leap out insistently. I ended up building a scraping tool to knock off the peaks, then skim coated and sanded the walls towards a relative smoothness. We chose a color of green that had a bit of life to it. It quiets down in the natural light, but maintains some intensity in artificial or reflected light. The photos above show both scenarios.
I suspect that most people think of walls as surfaces, but I like to treat them as spaces. Walls, like paintings, are best understood by their edges. The center is a more mysterious space with a disorienting habit of falling away– especially when color gets involved. I love that center, where a wall can act like a window.
