For the study, published in the Journal of Hospitality and Tourism Research, researchers at the University of South Brittany in France instructed 11 waitresses in five restaurants to wear the same T shirt in different colors--black, white, red, blue, green, and yellow. The waitresses were told to act the same toward their customers no matter what color shirt they were wearing.
What happened? When they were wearing red, the waitresses' tips from male customers were 14.6 percent to 26.1 percent higher. How about the tips left by female customers? The study showed that the size of their tips had nothing to do with the color of a waitress‘s clothing.
