Phenomenon caused by the presence of large quantities of suspended particles in the atmosphere which selectively remove the longer lunar ... visible wavelengths more than the ... green wavelengths.

OBS

When a month has two full moons the second is known as a "blue" moon, though it only rarely has a blue tint that unusual atmospheric conditions can supply. Occasionally the moon takes on unusual colors, but most often it tends to be reddish, reports Guy Ottewell of Furman University in Greenville, South Carolina. The occasional blue or bluish-green moon can take place when a lot of dust is present in the air, such as after a volcanic eruption, Ottewell notes in his Astronomical Calendar 1999.
