Occasionally, Tokyo Tower's lighting is changed to specific, unique arrangements for special events. The tower is specially lit for some annual events. Since 2000, the entire tower has been illuminated in a pink light on October 1 to highlight the beginning of National Breast Cancer Awareness Month. The tower has also had a variety of special lighting arrangements for Christmas since 1994. During New Year's Eve, the tower lights up at midnight with a year number displayed on one side of the observatory to mark the arrival of the new year. Special Japanese events have also been cause to light the tower in several nontraditional ways. In 2002, alternating sections of the tower were lit blue to help celebrate the opening of the FIFA World Cup in Japan. Alternating sections of the tower were lit green on Saint Patrick's Day in 2007 to commemorate the 50th anniversary of Japanese-Irish relations. On a few occasions, Tokyo Tower has even been specially lit to correspond with corporate events. For example, the top half of the tower was lit green to correspond with the Japanese premiere of The Matrix Reloaded and different sections of the tower were lit red, white and black to commemorate the first day of sales of Coca-Cola C2.[33] The tower was also uniquely lit for the new millennium in 2000 with Motoko Ishii again reprising her role as the designer.[34] In December 2008, Nihon Denpatō spent $6.5 million to create a new nighttime illumination scheme—titled the "Diamond Veil"—to celebrate the tower's 50th anniversary. The arrangement featured 276 lights in seven colors equally distributed across the towers four faces.
