Don't know about Colorado, but in WI, there are only two methods used for black bear: hunt over bait or hunt with dogs. Otherwise, you will have to hunt after dark, and that is never legal. Only rarely do you see a bear during the day. I might see one or two per year during the day on average in random places as I drive, walk, etc. In WI, you must apply year after year and only after 4 or 5 years will you get a tag. I tried the baiting method once - ended up bringing in every raccoon around and I only saw a big bear after bear season ended when I was trying to deer hunt - it was quite frustrating. I will stick to deer.
Maybe in CO you can do some long range spotting and shooting to increase your odds if baiting or dogs are not allowed. Best advice is to check with the locals to see what works in your area.
