You are probably noticing what is really an optical illusion. When the moon is particularly bright, especially if it is full, the sky immediately surrounding the moon does take on a particularly dark appearance. It is really the contrast between the bright moon and the night sky that you are noticing. There is some small degree of light coming from what look like empty parts of the night time sky, but it is very faint. During the day the extremely bright sun scatters so much light through earth's atmosphere that the heavenly bodies are completely obscured from view.

The Moon
Several factors cause the phases of the moon. The "light" side of the moon is light because light from the sun reflects off of it. (Interestingly enough, because of the way the moon revolves on its axis and revolves around the earth, the same side is light at all times.) The side that faces the sun is always light. As the moon revolves around the earth, the angle at which we see the moon changes, so we see different parts of the moon. This causes phases.

The light around the moon is called the corona. It is the outermost portion of the sun's atmosphere. The corona is always present, but except during an eclipse it is hidden by the glare from the rest of the sun.
The Moon is always spherical, or nearly so. However, the light from the Sun comes ... from the Sun, and we live on the Earth. So as the Moon goes around the Earth and the light comes from the Sun, our view of the illuminated area of the Moon will vary.It is this "sideways" view of the Moon in the sunlight that causes our perception of the phases of the Moon.
The light from the sun reflects light to the full moon as the sun is always just opposite the full moon except during the new moon time, where there is no moon to be seen.
The Moon isn't really changing its shape. It is always round. As the Moon moves around Earth, we only see the parts of the Moon that are lit by the Sun. The Sun's light bounces, or reflects, off the Moon.
many people think that the sky is blue because of the reflection of the earth. that is wrong. the sky is blue because of the gases produced in the sky. my point is, the sun goes down at night, and without light there can be no color. the only color that can be produced without light is black. there you have it. :)
A moon always revolves around its planet.
No, the moon is not always dark. It reflects light from the sun, so it appears bright in the night sky.
The Moon does not have its own light source, so its color at night is reflective of the sunlight it receives. The sky surrounding the Moon at night can vary in color depending on atmospheric conditions and location, but it is typically dark blue or black.
