Quick moving lights in synchronization. No sound or trails. Disappeared and reapeard on walk to apartment. Objects changed colors a lot

Quick moving bright lights. In synch. No sounds at all and flashed different colors. Happened during fireworks but very easy to tell its not fireworks nor a plane or helicopters in formation. Multiple witnesses. Dissappeared and reappeared in minutes on walk to apartment. It seemed to change speeds a bit but not a lot. The objects also seemed fairly close as in not extremely high but the objects still seemed smaller than crafts known of and the flight pattern was so consistent between the two lights that I truly don't believe it's drones being flown as the line between the 2 was absolutely perfect and did not change at all during flight.
