The term "Crimson Moon" often refers to a lunar event where the moon appears red or reddish-orange, typically during a total lunar eclipse. This phenomenon occurs when the Earth passes between the sun and the moon, casting a shadow that filters sunlight. The scattered light gives the moon its distinctive crimson hue. In popular culture, "Crimson Moon" can also denote various artistic works, including books, songs, and films. These works often explore themes of mystery, romance, or the supernatural, drawing inspiration from the captivating visual of a red moon in the night sky.
