One of the interesting observations of the Moon Eclipse Total is the appearance of the moon that will be reddish red. Some people call it the color of the moon when the total eclipse is 'blood red' or Blood Moon. The blood red color indicates the degree of dirty or clean earth's atmosphere.
The reddish red is not the real color of the moon covered by the shadow of the earth. The red color appears because sunlight is dissipated by dust and molecules in Earth's atmosphere.
