Looked where we had seen previously and noted one object with colored lights somewhat higher than our previous sighting

We had observed 2 nights ago multiple objects with flashing red, green, blue and white lights moving erratically in the sky. Last night we saw 2 white spheres in the same general location but they didn't appear to be moving so we dismissed that sighting. Tonight we again saw the colored lights in the same westerly direction from our position but could only see one and it was at a considerably higher elevation than our previous sighting. It appeared to be a bit farther away also but we could still note the erratic movements that were unlike any normal airplane or helicopter.
