Welcome to the OCDO forum, especially the Colorado contingent.
That said, let's take a crack at your question.
The first thing I'd suggest is to be fully up to scratch on the laws regarding open carry. Article 2 of the Colorado Constitution, specifically sections 3 and 13 are instructive. But there are a whole bunch of other things to learn about too. By reading about LEO encounters folks have experienced both here in Colorado and other parts of the country, you can learn a great deal about how to cope with the situation when it inevitably arises. By knowing the law, along with your rights, you're armed to handle that encounter.
Also recommended by most open carriers is to have a voice recorder to document any encounter should one arise. If you've got them saying something contrary to law, or infringing on your rights recorded for a judge to hear, odds are pretty good that will turn attention from you to the offending officer. In some cases, can also result in a hefty settlement paid to your bank account.
My best recommendation is to read, read, read... then read some more. Plenty of great information on this forum, and the more you know, the better prepared you are. Cases are discussed, such as St. John vs; Alamagordo. While that case was one from New Mexico, the fact that the district judge went to the additional trouble of publishing his opinion carries additional weight in other jurisdictions.
Don't fret about learning everything all at once, because the truth is, the whole open carry experience is an evolving thing, and new information and court decisions are emerging every day.
Good luck, and carry on!
