Sunset orange

Quick answer：

Sunset orange refers to the vibrant orange color that occurs at sunset, often seen in the sky or reflected in water. This term is often used to describe the beautiful hues of a sunset, which can range from pale orange to deep red or purple. The color is caused by the scattering of sunlight by the atmosphere, which filters out shorter wavelengths of light and allows the longer wavelengths, such as red and orange, to be more visible.
