This hue is inspired by the unmistakable yellow of taxi cabs—a color chosen not for flair, but for visibility. In 1907, a New York taxi company adopted yellow after a study suggested it was the easiest color to spot from a distance. The idea stuck, and yellow taxis became icons in cities like New York. Fun fact: New York City caps its yellow taxis at 13,587 medallions—and at its peak, a single medallion sold for over $1 million.
