Usually
“green” field color is used for acceptable risk ratings, “yellow” or “orange”
color for medium risk, which requires additional mitigation measures to reduce
it to acceptable “green” level and “red” color for unacceptable high risks,
which mean that job cannot be performed with this level of risk unless
mitigation measures reduce it to “green” level. Risk matrix setup determines
which level of Severity and Probability of the risk is “acceptable” by marking
these fields as “green” and which level is unacceptable, marking such boxes
into “red”, “orange” or “yellow” color.
