Huge flying circle object, w/ beautiful colorful trickling lights flying impossibly fast, then took a 90 degree turn into the clouds.

So last night around 10:30 I was outside walking some little ones and saw a huge flying circle object, with beautiful colorful lights flying impossibly fast, heading north from DT Bellevue. It appeared to be flying north and then did this insane 90 degree turn into the clouds.
So this happened while I was in Kirkland, north of / very close to the water. It WAS definitely cloudy but not directly over Kirkland, the clouds appeared to be further away like over Bellevue.
The whole incident lasted probably 8 to 10 seconds and then it was gone.
Again, taking into consideration the distance it appeared to be and relevant buildings and homes below it, it would have had to have been incredibly large, like 150 feet across kind of thing. The lights were like a flowing trickling effect, coming out from the center of the object to the edges and it was ALL different colors, beautiful colors. In fact the ONLY thing I could see were the lights and its shape, otherwise it was too dark to see the actual object itself.
And the object was completely round, meaning, not flying saucer round but like an actual upright circle flying towards my general direction.
