Welcome to space.com!

What vogon is saying is, our atmosphere changes the color.

Notice how on some days the sun is red at sunset? It's the same effect; the amount of color change depends on the amount of dust and moisture in the air between the earths's surface and the moon.

The dust & moisture Wayne mentioned, filters out the shorter wavelengths of light, i.e those shorter than yellow, hense the Moon, or Sun, or any bright astronomical object close to the horizon appearing redder than it naturally would normally.

Longer wavelengths penetrate dust, haze etc, far more than shorter wavelengths. This is why Infrared Telescopes are so good at looking inside nebulae etc. It's exactly the same principle.
