The phrase "once in a blue moon" means very rarely. A blue moon is the second full moon in a calendar month. Since there is a full moon once every 28 days, having two full moons in a month doesn't happen very often.

The moon is not 'blue'; the color of the reflected light from the sun on the side that faces the night side of the earth changes as the angle of the light passes through the earth's atmosphere, the distance that it travels through the air (refraction) and any particles or dusts suspended in that air. The 'blue' light is shorter frequency. This is similar to the phenomenon that the Moon's diameter seems larger at 'moonrise' and 'moonset' than it does at the height of the apparent arc.
If anything, the moon is various shades of grey; see the color photographs from the Apollo moon landings.

There is a song called Blue Moon. lol Here is the website where you can read more on it. It takes up different hues of colors. There are several pictures with some awesome colors in it. Blue included. http://www.colormoon.pt.to/
If you observe some particular features on the lunar surface through a telescope you will notice for sure some tiny differences in the hues of the various greys of the surface, as there are many different geological formations composed of different minerals, so there must be a difference, even though very subtle to our eyes, in the color. But to digital and analogic image capture devices it is an easy task to record color information with quite good accuracy, so it can be enhanced afterwords by digital processing to allow us to see it too!
In Photoshop you can try to increase the saturation of the image to show the colors of the moon using the "Hue and Saturation" tool or pressing CTRL+U, but because of the color temperature (white balance) is never at the right spot, one color tone is dominant and overwelms all other colors so the hidden details are not revealed and you get a blue moon or a orange one....

The moon looks pretty grey to me.
Anyway a "blue moon" is when there is more then one full moon in a month. It's happens rarely so that's why the phrase "once in a blue moon" means something that happens rarely. It has nothing to really do with color.

Blue? Who told you the moon was blue? It's white with a little tone of yellow, and that's because of the Sellenium.
