Alertmanager

You can now set the default colors used for message formatting when using the Alertmanager bridge:

bridges:
  alertmanager:
    config:
      # default HEX color codes to use for alert severity text
      colors:
        # -- HEX color code to use for critical alerts
        critical: "#f2748a"
        # -- HEX color code to use for error alerts
        error: "#f289f9"
        # -- HEX color code to use for warning alerts
        warning: "#fdcd36"
        # -- HEX color code to use for info alerts
        info: "#7aa2f7"
        # -- HEX color code to use for recovered alerts
        recovered: "#a8fd57"
        # -- HEX color code to use for default alerts
        default: "#585858"
