Detailed explanation-1: -The most striking thing about Mars’ appearance – whether seen with the naked eye or through a telescope – is its red color. This color is caused by iron in the rocks on Mars’ surface – the same thing that causes the red color in sandstone formations in the southwestern US.
Detailed explanation-2: -So, Mars is red because it has a layer of rusty dust covering its entire surface! Mars has some of the largest dust storms in the galaxy, in which the red dust gets whipped into the light atmosphere surrounding the planet. This is why Mars also appears to have a red sky.
Detailed explanation-3: -The blue color near the Sun is not caused by clouds of water ice, but by the Martian dust itself. The dust in the atmosphere absorbs blue light, giving the sky its red color, but it also scatters some of the blue light into the area just around the Sun because of its size.
