Firework laws in Unincorporated Arapahoe County confusion?

Ok. I live in Unincorporated Arapahoe County which is in Colorado and I know that in Aurora and Centennial all fireworks are illegal, but I know that the laws are different in Unincorporated. Anyways. What fireworks are legal and which are illegal for where I live. And If i was caught doing aerial fireworks what kinds of charges would I be facing. How much of a fine would i recieve and how much jail time if any?
