The Boston Celtics logo since the early 1960s features a leprechaun spinning a basketball, named Lucky. It was originally designed by Zang Auerbach, the brother of Celtics head coach Red Auerbach. For a long time, the logo's only colors were black, white and green. Then for the 1996–97 season, celebrating the club's 50th anniversary, the logo got a full-color treatment. Lucky's face and hands were both painted tan, while gold was included on the vest, bow tie and hat, as well as brown on the ball and shillelagh, and black on its pants and shoes.
