To curb smartphone addition, should parents drain the color from their kids' phones?
From Is the Answer to Phone Addiction a Worse Phone? in Saturday's New York Times:
“You don’t buy black-and-white cereal boxes, you buy the really stimulating colored one, and these apps have developed really cool tiles, cool shapes, cool colors, all designed to stimulate you,” Ms. McKelvey said. “But there’s a vibrant world out there, and my phone shouldn’t be it.”
She decided to make the switch to gray as well. But it was tricker than she expected.
“It took like 40 minutes to figure it out. They buried the setting,” she said. “You have to really want to do it.”
Here's how (from Lifehacker):
In iOS 10, go to Settings > General > Accessibility >Display Accommodations >Color Filters. Switch Color Filters on and select Grayscale. To easily toggle between color and grayscale, go to Settings > General > Accessibility > Accessibility Shortcut > Color Filters. Now, you just press the home button three times to enable grayscale. Triple-click again to go back to color.
The idea comes from former Google design ethicist Tristan Harris, who made the media rounds last summer, long before the California State Teachers Retirement System asked Apple to make it easier to parents to curb iPhone use.
