"Two years ago, we painted a major living area in our home—a large, open-concept space that contains our family room and kitchen, with high ceilings and lots of natural light. We took it from a garish mustard yellow to white. The room now looks so light, so bright, so green.
How could this be? It turns out, our home is surrounded by trees, and during the day, the light flooding through the windows carries a green tint, which shows up on our white walls. We hadn’t considered this possibility when we’d picked what we thought was the perfect shade of white. Oops."
