Our Moon’s actual colour is off-white brown-gray but Earth’s atmosphere modifies our views of the moon.
Tiny air molecules in the layers scatter light that hits them, and their structure causes blue light to scatter more readily than red or orange.
During a lunar eclipse, one can witness “Red Moon” because the only sunlight reaching the Moon passes through Earth's atmosphere.
“Pink Moon” is often witnessed when it’s the first full moon of the spring season.
When the Moon is “Orange” it is because the atmosphere is filtering out the shorter wavelengths.
A moon seen near the horizon can also found to be “Yellow” in colour.
A blue or purple-colored moon is very rare and can indicate a moon seen through an atmosphere carrying larger dust particles.
