We all know that Moon does not have it's own light, It Takes from the Sun. Sunlight is a mixture of various visible color. Now when Sunlight fall on the moon, It reflect all visible colors equally.Because of that moon appear or look like White.

                   However, during a lunar eclipse when the earth is exactly between the sun and the moon, the moon appears red. This happens due to earth's atmosphere.

When Sunlight passes through earth's atmosphere Scatters the colors of the sunlight having shorter wavelengths. However, the red color which has the longest wavelength is least scattered. Hence it makes moon appear as Red or We called Blood Moon.
