The color can only be set per alias while our alias is the dispatcher name, there is no easy way to change the whole palette per metric. Closing .

actually this can be done through regex, here is the json

 "seriesOverrides": [
            {
              "alias": "/timeout/",
              "color": "#0A50A1"
            }
          ],
