Ramsoy says a grayscale screen puts you more in control of your actions. Instead of a cacophony of colorful apps trying to outdo each other for your attention (and often succeeding), the grayscale equalizes everything you see on your screen. Nothing looks more attractive than the app next to it. You'll be more likely to use your phone mindfully and with better intention since you are no longer subconsciously being pulled in different directions by the apps themselves.
