The NBA launched its inaugural Green Week initiative in April of 2009. The program was developed to promote environmental education to the league's fan base. As part of the project the Bulls donned hunter green uniforms for a game against the Philadelphia 76ers on April 9, 2009. Besides the on-court program, the Bulls facilitated neighborhood clean-up programs in the area surrounding the United Center. As a side note, the Bulls defeated the Sixers that night, 113-99. Maybe green is good luck for more than just the Celtics. The Chicago Bulls name is known around the world from the dominant reign of Michael Jordan, Scottie Pippen, Dennis Rodman, Steve Kerr & other greats throughout the 90's. The iconic logo has been worn by some of the all-time greatest basketballers since 1966.
