Show me in the Colorado Revised Statutes where there's any such law entitled 'Make My Day'.
I see Colorado Revised Statutes 18-1-704.5, entitled "Use of deadly physical force against an intruder." but nothing as sensationalist as 'Make My Day' or 'Shoot The Carjacker' or 'Eat Lead You Dirty Hispanic Heathen' or 'Wildly Fire Shots At Shadows'.
That we let the media punks get away with this crap is the same as letting gun banners declare things to be 'Saturday Night Specials' or 'Assault Rifles' or 'Cop-Killer Bullets' or 'Minority-Seeking Missiles'.
Ridiculous. Good thing nobody reads newspapers and local news websites except for us anymore. Golly, they may be negatively influenced by agitation propaganda.
Did a couple searches and it seems that it has been a fairly wide used nickname for the statute that allowed such home protection since 1985. I would guess that if enacted today, it might have a different nickname.
Moffat County Sheriff has this:

They are calling 18-1-704.5 a “Make My Day” law.
I think it is better called the castle doctrine in this specific case. But, CO does allow the use of deadly force anywhere to protect yourself against deadly force.
