Blue is the perennial favorite for a reason.
In one widely cited color preference dataset, 42 percent of people named blue as their favorite color.* In The Day the Crayons Quit, by Drew Daywait, it was Duncan’s favorite, too. He used it so enthusiastically to color oceans, lakes, and rivers that he couldn’t even see out of the crayon box anymore.
Thankfully, your socks will still be visible. Just a flash of brainy blue brilliance between your shoes and your hem, for those who know to look.
From a scientific perspective, blue is often associated with calm, focus, and clarity. It’s associated with lowered heart rate and steadier rhythms. The brain’s idea of a deep breath, in color form.
