Saw 2 bright white lights, 1 red light, and 1 green light hovering above 35E North of HWY 96, Next to Polar Lakes Park.

Aircraft hovered over roadway as we approached, we overtook it at 60 MPH.  After we passed it it strafed left and right a few times then headed West.
It appears to be drone, however, as I drone pilot, I did not recognize the shape or lights at all. It did not strobe in the way that a normal drone or manned aircraft would.
Everyone in the vehicle saw it as well.
Light pattern was Whites on the outside, with red and Green in the middle.  Like this -> W R G W  Aircraft appeared to be about 1 meter in width and flying at an altitude of 100'  A drone in that size category is many thousands of dollars (and difficult to fly) which would place it in the professional category, since no events or construction are going on in the area, it would be unusual for an aircraft such as that to be in there area and flying at night and over a road (both of which require extensive permits from the FAA).
