The Moon turns red for the same reason that sunsets are red.

The red color is created by microscopic aerosols present in the atmosphere which scatter blue light and leave the red behind.

In rare cases, the moon can also turn blue. The color is then triggered by volcano ash or wilfire aerosol found in the smoke.

Volcanic and smoke aerosols of just the right size – about 1 micron in diameter – scatter all the red out of moonlight and turn the lunar disk blue.
