Two objects with pulsating lights in Seattle over Puget Sound.

I woke up at 3:40 AM and looked out my downtown apartment window to the Southwest. My apartment is on the 13th floor. Between the tall buildings, over the Puget Sound, I saw a stationary, pulsating light that changed color from blue-white to red, yellow, and green. I awoke my partner and she also saw the object. At one point a smaller white light seemed to emerge from the bottom of the craft, but it disappeared immediately. With binoculars we could make out the colors better, but could not discern a shape to the object. I took several pictures with both digital and film cameras. If the photos show anything I will submit them to this site. After watching the lights for about 20 minutes, I noticed a second craft to the west of the original one. It was identical in appearance, with pulsating blue-white, red, yellow, and green lights. The lights on the two objects did not appear to pulse in unison. The second craft also appeared to hover without motion over the Sound, perhaps a mile or so from the first. The first craft was lower in the sky than the second, not very high in the air. At 4:24 AM, the first craft slowly disappeared behind a building after arcing downward toward the west. The other craft remained stationary and I finally fell asleep.
 My partner and I are professional women in our 30s.
