If I pay for remodeling costs in my daughter's home in CO, will CO Medicaid count that money in the look back period?

If you need care within 5 years of that remodel, yes Medicaid will count that money as a gift even though the remodel is for you. The reasoning is, daughter profits from the remodel if she sells her house. There will be a penalty.

A better plan may be for you to take that money and transition into a good, reputable senior community (near your daughter) that has a continuum of care levels. What will your daughter do if/when you become 100% incontinent for both urine and bowel? Or start wandering outside at night? Or leave the empty pot on the stove with the gas on? Or all of the above?

It is understandable (and common) for people to romanticize their sunset years. No one ever wants to entertain the thought of becoming an unmanagable, exhausting burden to initially willing and well-meaning adult children. But if you plow all your money into a home remodel (which may indeed disqualify or delay your Medicaid and make your daughter's life miserable) what will happen if you don't have enough funds for your daughter to hire in-home aids, let alone Memory Care -- or LTC (which is the only level of care that Medicaid pays for in most states)? If your money is tied up in a home, does that mean she'd have to sell and move the home to use that money to help with providing your care so she doesn't burn out?

Please read the plethora of posts on what this disaster looks like from an adult child's perspective under the Burn Out care topic. Frankly, it's pitiful and often avoidable.

You need to consult with a Medicaid Planner for her home state (assuming you do move there). It's too important of a question to leave to non-professionals on an anonymous, global forum.
