The heavy snow in Jiamusi 10 is yellow and the sky is orange. What's going on here?

Snowflakes turn yellow because they are mixed with yellow dust rising from the desert.

On the East Tianshan Mountains and Altai Mountains in China, sometimes the falling snowflakes are yellow. In the Alps of Europe, yellow snow also began to fall.

Yellow dust from the Sahara desert crossed the Mediterranean Sea from the air and dyed the snowflakes there yellow.

According to the above situation, the metaphor of "white as snow" in literature may not be applicable in science sometimes. Even the cleanest snow will have a special color and its own structure when it falls to the ground. For example, the soft snow that has just fallen is often light blue in color; The fine snow from the wind shines like silver; On the glacier, the Chen Xue, composed of coarse snow and fine snow, has a light gray surface and a light green depth.
