What is that multi colored light next to your moon?

The multi-colored light next to the moon is likely a phenomenon known as a lunar halo, which occurs when moonlight is refracted through ice crystals in the atmosphere, creating a ring of light around the moon. Alternatively, it could be an optical illusion or atmospheric conditions like light pollution or city lights reflecting off clouds. In some cases, it's also possible for bright planets or stars to appear near the moon, creating a colorful display.
