The updated state Covid-19 dial went in effect over the weekend, placing counties in new levels.
Chaffee, Park and Fremont counties are now in the less restrictive Yellow level which includes a 7-day instead of a 14-day metric for quarantines.
There are also changes to capacity level caps.
In level Yellow, businesses can have up to 50 percent or 150 persons using a space calculator.
The changes come as Covid-19 cases and hospitalizations continue to decline in Colorado.
Lake County remains in level Orange while Saguache and Custer counties move down to the Blue level.
