When you open the Affected SLAs section of a request, you will see that the affected SLAs of the providers that you work for are highlighted. The highlight color indicates how close the next SLA targets are to being violated. These targets can be response targets or resolution targets.
The highlight colors are the same as the colors used for the request header. Green means that there is still more than an hour available before the next target is violated. Yellow indicates that there are more than 20 minutes left. Orange tells you that there are less than 20 minutes left and red means that the target has already been violated.
