Need help installing Ring Wired Doorbell!

 I installed the ring doorbell and there is no power, the ring doorbell device won’t turn on. Doing some research, most of the photos or videos I’ve seen, users have a red and white wire. Mine comes with orange in the transformer. I am not sure if I don’t have enough voltage, but transformer says 16V. I have tried different installing wires and still nothing, I am stuck! Please help!
