Blue Moon Tourism Myths: Can You Actually See the Moon Change Color With the Naked Eye? A Viral TikTok video claims that during a "blue moon" event, the moon physically changes color to a vibrant blue, sparking a surge in interest. However, this is fake—a "blue moon" refers to the second full moon in a calendar month, not an actual color change. The moon may appear blue due to atmospheric particles from volcanic ash or smoke, but only rarely, and the viral proposal for "blue moon viewing glasses" to see it is a hoax.
