Canada's tallest free-standing structure lights up the Toronto skyline with its festive red, green and white colours. The CN Tower often changes its nightly colours during holidays, sports, and special events including a lighting tribute in early December to the late Nelson Mandela. The tower turned blue to welcome the royal baby boy; the grand announcement flashed in the sky for eight minutes. The tower's spectacular LED illumination system can produce up to 16.7 million colours and can be controlled from a single computer console. The city also considers special lighting requests for personal occasions like birthdays and anniversaries. Now that's one thoughtful (and pricey) birthday present!
