The moon often appears to be in different colors throughout the year, but its actual color is grey. Unlike earth, where there are objects colored in different ways due to its atmosphere, water, and life; on the moon, there is no such atmosphere and life. Instead, the moon contains magnesium, calcium, iron, aluminum, oxygen, feldspar, silicon, and pyroxene. These all basic minerals collectively give grey color to the moon.
Moreover, we also find many dark spots over the moon from the earth. All those spots are the result of huge amount of volcanic activity and this activity has also formed various types of rocks over it. These volcanic activities gave Lunar Marias, which are the less reflective spots on its surface. This is the reason why we can see colorful diversity on the moon from earth.
Every color of the moon that we see from the earth is due to the material reflectivity of light. The color outside the earth’s atmosphere is provided by the sunlight and when it gets reflected from the surface of the moon to the earth, its color changes due to the earth’s atmosphere.
