Why the Moon can be colored yellow?

"Yellow moon follow us! If we walk, he also runs, if we ran, he also ran." Is it true that the moon is following us all night long yellow from start to finish? Actually the moon is not always yellow, depending on the time and conditions when we see it, the color of the moon varies slightly. When the new moon appears and when the moon began to sink toward the south at dawn, he colored red.

Because at those times the distance that must be refracted sunlight from the atmosphere to the earth's surface very much, so that short wavelength light and blue will collide with the dust, clouds, and water vapor in the atmosphere so that light will be reflected back while wave lengths of light reddish color is refracted so that we will see more months of red and yellow.
On a clear day the moon is in the sky is blue. This occurs when the air cleaner so that the light that passes through Earth's atmosphere will not be reflected. However, due to air pollution, the sky grew dirty. That's why today we hardly see the moon is blue again. Instead it will be easy for us to see the yellow moon.

So we more often see the moon is yellow because of the increasingly severe air pollution causes the blue light of the moon colliding with objects in the air pollution so that the light is reflected and only the yellow light is refracted until it can be seen on earth.
