There really is not much is any "drone law" in colorado state law for hobbyists.
Of course there are some state and federal land use regulations for some parks and such if your physically going into government controlled public land than you should know the rules before you enter.
Follow faa guidelines, and use common sense, don't purposely endanger anyone (common sense).
If your not doing stupid stuff no one should bother you.
If anyone does bother you THAT IS NOT LAW ENFORCEMENT I recommend you DO NOT ENGAGE THEM IN ANY WAY, tell them to GO AWAY and if they don't LEAVE YOU ALONE you should call law enforcement.
Photography is not a crime.
Flying a UAV is not a crime.
Stop thinking of yourself as a potential criminal.
