Blue hour is a fascinating natural phenomenon characterized by a distinct color temperature. This ethereal time occurs twice a day, around dawn and dusk, when the sun is below the horizon and produces a unique bluish-grey light. The color temperature of blue hour falls between 10,000K and 12,000K, creating a surreal and enchanting atmosphere. This low color temperature is caused by the scattering of sunlight by molecules in the atmosphere, resulting in a dominant blue hue. The warm colors of the sun are filtered out, leaving behind a twilight-like effect that lingers for a brief period.
