Noisy colors

The Washington Post looks at — listens to different colors of noise: “Beyond white noise: How different ‘color’ sounds help or hurt” (gift link).

I often used brown or pink noise in my office to cut sound from the hallway and a nearby classroom. I never fell asleep, but gosh, could I concentrate. From a 2012 post about a now-defunct Mac app: “Without pink noise, I’d get nothing done in my office.”

Today there are many apps and websites generating noisy colors. Here’s a free site I just discovered: noisetool.
