Looked cylindrical from the lights, changing colors from white to red to orange then yellow back to white, .

My husband took the dog out and called me out there was a I'm guessing cylindrical craft( the lights were in a straight horizontal line) in the distance moving very slowly horizontally and it was changing colors from white to red, orange then yellow and back to white. From where we are it had to have been pretty large and the approximate location would have been over the mentor headlands which is on lake erie. There's alot of beach and nothingness out there it's a park and lots of wild land I guess you would call it, dunes, scrub grass ect. We watched it for a few minutes until we couldn't see it anymore because of the house across the st. We live approximately 5 miles away that's why I say it had to have been pretty big but we also don't know how far off shore it was, how high in the sky ect...
