changed images every 40 seconds to feature each Disney castle and the date its park opened: Disneyland, 1955; the Magic Kingdom, 1971; Tokyo Disneyland, 1983; Disneyland Resort Paris, 1992; and Hong Kong Disneyland, 2005. The decorations were removed in late September 2006. The castle's most recent and current redecoration is to celebrate Walt Disney World's 50th anniversary, known as "The World's Most Magical Celebration", which began on October 1, 2021, and will last until March 31, 2023. The design was first revealed on February 19, 2021, with most of the decorations being installed from March 11 to April 16, 2021. The "EARidescent" pieces, as Disney refers to them, include gold detailing, royal blue jewels, shimmering pearls, draping and ribbons on the castle's turrets. The final decoration is a giant 50th crest that covers the clock on the front face of the castle, which was installed the night of July 22, 2021. At night When the sun sets, the castle is illuminated by SGM Palco LED lighting fixtures placed on different castle levels and surrounding areas, providing an effective range of 16.7 million colors. The castle itself plays a role in the Magic Kingdom's former fireworks show, Wishes: A Magical Gathering of Disney Dreams, in which it changes color in synchronization with the dramatic music of the display. The same color changing and effects occurs for the other fireworks shows: HalloWishes (in Mickey's Not-So-Scary Halloween Party); Magic, Music and Mayhem (during Disney's Pirate and Princess Party); and the Christmas fireworks show Holiday Wishes during Mickey's Very Merry Christmas Party. The castle's projection mapping technology has been used in several night events, such as their current fireworks spectacular, Disney Enchantment, and its predecessor, Happily Ever After. During the holiday seasons, various shows have utilized projection mapping, including Hocus Pocus Villain Spelltacular, along with the Halloween themed Disney's Not-So-Spooky Spectacular and Holiday overlayed show, Minnie's Wonderful Christmastime Fireworks. At the park's closing, the nightly "Kiss Goodnight" was performed, in which Roy O. Disney's dedication speech for the Magic Kingdom is played throughout all over the park accompanied by Disney music which changes with the colors of the castle. Even when the park closes before 11pm (23:00), the show is performed a second time at 11pm (23:00), providing entertainment for guests of Disney resort hotels bordering the Seven Seas Lagoon. This practice seems to have ended in 2020 after the park reopened from Covid-19.
