The blue moons are not typically blue in color but there is the possibility for a blue-like tint on the moon.
Space.com provided one example of how a blue moon occurs is if there's been a recent forest fire or volcanic eruption that pumped significant smoke or ash into the upper atmosphere. It is then that the possibility for the moon to take on a bluish hue.
Two notable events when smoke and ash cause a blue-hue on the moon were during the eruption of Mount St. Helens in 1980 and Mount Pinatubo in 1991.

"The second full moon that appears in a calendar month is named blue moon. But it will not look blue in colour. We call it a blue moon because this phenomenon happens only every 2.5 years," said AstroVed.com Director Maya Benkovich to AsianAge.com.
According to Universe Today, Astronomer and Publicist for Australasian Science magazine David Reneke said, "Blue Moons don't have any real significance scientifically but they're fun to look at. Anytime you can get people out to look at the real sky to me is a great plus, enjoy it while you can this Friday night and while you're looking moonward, think of Neil Armstrong, OK?"
The next blue moon is set for July 1 and 31st of 2015.
