Why does the moon sometimes look like a different color than usual?

The moon can appear in different colors due to atmospheric conditions. When it is low on the horizon, the moon's light passes through more of the Earth's atmosphere, scattering shorter blue wavelengths and allowing longer red wavelengths to dominate, giving it a reddish hue. Additionally, factors like air pollution, dust, or smoke can further affect its color. This phenomenon is often most noticeable during moonrise or moonset.
