Orange firey orbs flying over neighborhood

Orange orbs began to appear just southeast of our neighborhood and flew in a northern direction over the Pensacola international airport. They appeared two at a time and a final single one appeared. They started off as a red color, changed to orange, then yellow, and back to orange, then just disappeared. My wife said they looked like fire in the sky. They traveled very slow, then at one point seemed to hover in the sky stopped and then just move off and completely disappear. They seemed to be about the size of a basketball, but distance was difficult to determine because of their size. We do live less than 10 miles from the Gulfbreeze Shoreline Park and they seemed to originate from the direction of Gulfbreeze.
