In an effort to break my smartphone addiction, I’ve joined a small group of people turning their phone screens to grayscale — cutting out the colors and going with a range of shades from white to black. First popularized by the tech ethicist Tristan Harris, the goal of sticking to shades of gray is to make the glittering screen a little less stimulating.
