If your ceiling device is hot and the neutral is being turned on/off black and red will be hot whether the switch is on or off.
The color of the wire going down to the switch and back up is irrelevant and some electricians will tape the white wire to indicate that it is a switch wire.
Your switch could also be hot and supplying power ( there will be extra connections and wire nuts )
black and red wires could also be for three way switches and that requires diagrams - but you should know by now if you have two switches to turn a light on.
A potential can show at a switch if you don't unscrew the bulb.
