Exactly as described, this identifies whether this row's KPI thresholds apply to green in-contract traffic or yellow excess traffic within the parent profile. Because green and yellow traffic are generated at different bandwidths per the profile's own bandwidth and excess-bandwidth settings, and typically carry very different SLA expectations, this color tag is what lets the same KPI profile grade in-contract traffic strictly while grading excess traffic more leniently or not at all. For example, a KPI profile row for green traffic might require zero frameloss while the corresponding yellow-color row for the same PCP tolerates significant loss, reflecting that yellow traffic is expected to be discarded first under congestion.
