What's with colorful clouds in the sky?

Colorful clouds appear in the sky, which is a typical phenomenon of "Japan and China". Under the right weather conditions, sunlight forms a right angle with the clouds. 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 clouds:

1. Clouds located at 1 to 4 degrees away from the sun;

2. Clouds are thin clouds with even water droplets, such as Altocumulus Cloud, cirrocumulus, especially lenticular cloud. Rare clouds such as mother-of-pearl will form very bright colorful clouds;

3. On a sunny day.
