Strange colored lights blinking and moving erratically in south Denver sky.

I first noticed 2 distinctive lights. one red and one green. The red light was in the upper left and the green light was to the bottom right.

The lights were solid, then they began to blink. Both started blinking in a pattern that was frequent in wavelength like that of a plane, but then they started blinking independently instead of at the same time. Then the green light went out and the red light started moving up and down erratically and very precisely.

Then the green light came back on and blinked very erratically and the red went off. It then flew overhead at incredible speed from the north sky to the south sky and descended out of view. When it flew overhead, it was pure silence.

My friend who also saw it accounts that he saw blue and white lights too. He was certain he saw them, but I am certain I did not. We both watched very intently. No craft was actually seen, only two lights.
