What is pink rainbow called?

A pink rainbow is commonly referred to as a "pink rainbow" or "red rainbow." It occurs when the sun is low on the horizon, often during sunrise or sunset, and the light is scattered by atmospheric conditions, such as moisture or pollution, which enhance the red and pink hues. Unlike traditional rainbows, which are formed by refraction and dispersion of light in water droplets, a pink rainbow is more of an optical phenomenon influenced by the angle of sunlight and the surrounding environment.
