During this pandemic, the state is working to make life as sustainable as possible, while ensuring
we do not surpass our public health and health care capacities. Carefully maintaining the
effective reproductive or R number at or below 1 helps prevent the exponential spread of the
COVID-19 virus. Different levels of “openness” that are standardized at the county level will help
maintain this delicate balance. This framework recognizes unique local circumstances and uses
an intuitive dial to visualize a community’s success in containing the spread of COVID-19. By
increasing simplicity and predictability, we can give local communities another tool to make life
amidst the pandemic more sustainable until COVID-19 vaccines become widely available. This
dial went into effect Tuesday, September 15, 2020, and was updated to include a sixth level on
November 20, 2020. Dial 2.0, with increased incidence metrics for each level, went into effect on
February 6, 2021. On March 24, the state implemented Dial 3.0, which makes it easier for counties
to enter Level Green and loosens some restrictions in Level Blue.
We heard from stakeholders that
the colors should match Colorado’s
iconic fire-risk warning system. So,
we switched to make the green for
Protect Our Neighbors, and the blue
for Level Blue: Caution. We also
flipped it to match the orientation
as the fire warning system, with the
left side for the least risk, and the
right for the most risk.
THIS DIAL HAS SIX LEVELS:
• Level Green: Protect Our Neighbors
• Level Blue: Caution
• Level Yellow: Concern
• Level Orange: High Risk
• Level Red: Severe Risk
• Level Purple: Extreme Risk
The goal of each level is to strike that important balance between enabling economic and social
activity while ensuring that our testing, contact tracing, and health care systems are able to
contain the virus. Each level is defined by objective scientific metrics and has associated capacity
limitations. A community will move between levels based on the metrics and based on local and
state consultation to ensure unique local factors are appropriately considered. This tool will add
simplicity and predictability to how we open -- or close -- based on virus transmission levels.
This tool can be used by communities to implement locally-driven strategies to achieve the
desired level.

WHAT DO THESE LEVELS MEAN?
Each county is at one of six levels. Each level has associated capacity restrictions.
At one end of the spectrum is Level Green: Protect Our Neighbors, the level where a county is able
to exercise local control over reopening. At the other end of the spectrum is Level Purple: Extreme
Risk, which entails significant closures.
In between Level Green and Level Purple are four intermediate levels as defined by the public
health order. Level Yellow: Concern is the baseline, meaning it reflects the Safer at Home
capacities we followed in the spring of 2020. There is a less restrictive level -- Level Blue: Caution,
for counties that have low virus transmission, but have not yet achieved Protect Our Neighbors.
A more restrictive level -- Level Orange: High Risk --, is for counties that are seeing increases in
the metrics and need to take action. The second-most restrictive level, Level Red: Severe Risk, is
for counties with high levels of transmission, hospitalizations, and positivity rates. Most indoor
activities are prohibited or strictly limited, and outdoor activities are encouraged as an alternative.
In this way, we’ve moved away from reopening as a lightswitch (open or closed), and added more
steps where communities can gradually reopen or become more restrictive based on what is
happening with the virus locally.
WHAT METRICS DEFINE THESE LEVELS?
There is no one metric that tells the full story, but
together, three key metrics can help us understand
the fuller picture. These metrics are:
1. New cases -- a measure of how much the virus
is circulating in a community.
2. Percent positivity of COVID tests -- a measure
of how widespread infection is and whether
there is sufficient testing occurring.
3. Impact on hospitalizations -- a measure
of the impact on hospitals and how many
cases are severe, by looking at the number
of new hospital admissions and whether
hospitalizations are increasing, stable, or
declining.
In our draft, we proposed six
metrics. We revised this down to
three in response to stakeholder
feedback that the metrics must be
simple and objective. Additional
metrics, such as the other three we
proposed -- the direction of the
epidemiological trend, anticipated
future risk factors, and progress
towards achieving Protect Our
Neighbors all are important but are
best interpreted while considering
local context. So, they may -- and
should -- be discussed during
consultations between state and
local officials but are not part of
measuring the dial phase.
