UFO Sighting in Denver, Colorado on June 9th 2015 – Drone? type object Hovering of Capitol Hill Area – Denver

Woke to get a drink of water around 12:30 Am. Noticed bright light hovering over Cathedral Basilica of the Immaculate Conception off Colfax Ave. Looking out my apt window, which faces Cathedral Basilica of the Immaculate Conception this object moved back and forth (north, south) then hovered at times and moved up and down right around area of the church over Colfax Ave. At first it was bright orange / red then descended behind the buildings and came back around 5 minutes later... Then it starting changing colors from red/orange to green to red. Mostly green color and appeared to have a green ring around it. It started moving towards my apt window then turned back and descended behind the buildings again, Could have been a drone..I took some footage through my phone camera but the footage doesn't show how bright the colors were with the naked eye.
