Only "permissible fireworks" (non-aerial, non-explosive ground devices) are legal statewide in Colorado; possessing or setting off any other fireworks is illegal (C.R.S. 24-33.5-2001(11), 24-33.5-2002(5)). Cities, towns and counties may further restrict or ban the sale, use and possession of permissible fireworks, so check local rules (24-33.5-2007). Unlicensed people may not bring any fireworks into Colorado (24-33.5-2005(1)).
“it shall be unlawful for any person to possess or discharge any fireworks, other than permissible fireworks, anywhere in this state.”

Each rule below is the full statewide entry, with the official source it rests on and the date it was last checked.
Colorado allows ground and novelty fireworks only: fountains, wheels, ground spinners, sparklers, snakes, and novelties. Firecrackers, bottle rockets, Roman candles, and any aerial or exploding device are prohibited statewide.
“"Permissible fireworks" do not include aerial devices or audible ground devices, including, but not limited to, firecrackers.”

Colorado's fireworks law sets no statewide dates or hours for using permissible fireworks; cities, towns and counties may further regulate or ban their use, so the days and times you may set them off depend on local rules — check your city or county (C.R.S. 24-33.5-2007).
“This part 20 shall not be construed to prohibit the imposition by municipal ordinance of further regulations and prohibitions upon the sale, use, and possession of fireworks”

In Colorado it is illegal for anyone under 16 to buy fireworks, or for anyone to give or sell them to a person under 16; under-16s may possess and set off permissible fireworks only under adult supervision (C.R.S. 24-33.5-2002(1), (2), (6)). Buy only from a Colorado-licensed retailer: an unlicensed person may not bring any fireworks, even permissible ones, into Colorado, and aerial or exploding items legal in Wyoming are illegal to possess or use here (24-33.5-2005(1), 24-33.5-2002(5)).
“it shall be unlawful for any person who is under sixteen years of age to purchase any fireworks, including those defined as permissible fireworks”
