The reddish tint cast on the moon during a lunar eclipse has to do with the Earth’s atmosphere impacting the sunlight. The Earth is shielding the moon from most of the sun’s rays during a lunar eclipse.
The sunlight that does reach the moon is from the outer edge of the Earth. That light is passing through our atmosphere and the blue light gets scattered, but the leftover light gets bent back to the moon making it glow red. This scattering of light in our atmosphere is why the sunrise and sunsets appear reddish orange, too.

Wolf: Each full moon is given a different name. The wolf moon is the name given to this full moon in January. These names usually come from folklore. According to the Farmer's Almanac, the wolf moon got its name because wolves would howl outside of villages when they were hungry.
When to watch?
The moon passes into the Earth’s outer shadow around 9:36 p.m. Jan. 20 but it will be hard to notice any changes. At 10:33 p.m., the partial lunar eclipse will begin as the moon passes into the Earth’s inner shadow (umbra), and at this point it will start to dim and become red.
The total lunar eclipse begins around 11:41 p.m., and at this point it will have a reddish tint. Around 12:12 a.m. Jan. 21, the greatest eclipse will occur. The moon will go back to a normal color around 1:50 a.m. and the eclipse will be completely over by 2:48 a.m.
