Silent low flying small saucer shaped craft

I first noticed a bright orange light while traveling on Rt. 140 from Bellingham towards Franklin. While stopped at a red-light on the highway bridge I noticed the light traveling over the tree-line towards the center of town. The light was bright enough that as I got closer to it I could see it and track it clearly through the trees. Way too low to be a plane and I rolled down the window to see if I could hear a helicopter (it was silent). I watched it fly fast above the trees about a half mile then stop (hover) somewhere between a shopping plaza and beaver st. I arrived at my destination at CVS and I could still see the light- I was closer and noticed there was an orange light in the center and a blinking green light on one side and a blinking red light on the other. The craft then started moving again but directly towards me (standing in the CVS parking lot) slowly. It passed over my head then over the roof of CVS and even through the glare of the CVS lights I was able to make out grey circular shape around the lights. It was hard to tell how large it was because I couldn't really tell how high up in was maybe 100 ft over the roof of the CVS and roughly the size of a small car. I was freaked out when I saw the craft shape and went into the CVS when I came back out two minutes later I could no longer find the craft. It was completely silent I could not even hear a drone propeller. The sky was also clear very few clouds.
