Why are there colorful auspicious clouds?
The diffraction angles of different colors are different, and the bright area of one color light appears in the dark area of another color light, gradually forming a color sequence. The farther away from the sun, the lighter the color. Because clouds are distributed in irregular sheets, irregular sheets of colorful clouds are produced.
Extended data:
When sunlight passes through the clouds, the water vapor in the clouds above separates the solar spectrum through refraction and reflection, thus scattering seven colors of light. There are three main conditions for the formation of colorful auspicious clouds.

2. Clouds are thin clouds with uniform water droplets, such as altocumulus clouds and cirrocumulus, especially lenticular clouds. Rare clouds such as mother-of-pearl will form very bright clouds;
