Flashing red, blue, white, green, and yellow. Slowly and quickly zooming back and forth in the sky. As I was walking outside to check on my horses I looked up and saw flashing lights in the distance. I watched it for a while, then looked back minutes later and the same one was still there. At one time there were two near each other. I thought they were planes but the same ones were moving back and forth in the sky, and had two different obvious speeds, one very fast, and then very slow. I went back inside and soon lost interest and lost sight. I didn't have a camera on me.
