Taiwan taxis all yellow color. Women passengers are advised to call a taxi company for pick-up for safety reasons.
The first yellow taxis appeared in New York around 1907. A man there was buying taxis from France to use in the city. He found out that yellow is the easiest color to see from far away, so he painted all of his taxis yellow. Ever since then, yellow has been a popular color for taxis.
