What does a total lunar eclipse look like from the earth and why?

During a total lunar eclipse, the Earth passes directly between the Sun and the Moon, casting a shadow that completely covers the Moon. As a result, the Moon takes on a reddish hue, often described as "blood red," due to Rayleigh scattering of sunlight through the Earth's atmosphere, which filters out blue light. This phenomenon creates a dramatic visual effect, making the eclipsed Moon appear darker and more colorful compared to its usual brightness. The entire event can last several hours, with totality lasting up to about an hour and a half.
