What color is the sky on Mars?

Mars is the fourth planet in the solar system from the inside out. It belongs to the earth-like planet, and its diameter is half that of the earth. Due to the axial tilt, its rotation period is almost the same, and it takes twice as long to make a turn. The West called it the myth of Mars, the god of war, and China called it the "soul". The orange appearance is caused by hematite (iron oxide) on the surface. Mars is basically a desert planet with sand dunes and gravel on its surface and no stable liquid water body. The atmosphere dominated by carbon dioxide is thin and cold, and dust is suspended in it, and dust storms often occur every year. The poles of Mars have polar caps composed of water ice and dry ice, which will fluctuate with the seasons.

So the sky on Mars should be white or colorless.
