It should be noted that the orange-yellow indication is not sufficiently accurate.
The correct meaning of the orange and yellow callsign is that the information associated with this callsign is managed by someone else. This type of callsign is most commonly seen in situations involving special stations or club stations. Additionally, many international hams manage multiple callsigns under a single primary callsign (without needing to create separate accounts). The most common situation is when someone helps add a new callsign to the database. When a new callsign is registered on qrz.com, the callsign itself is not entered into the database, so the user does not have ham member status and cannot be found. In this case, volunteers or others need to help with simple information entry. After someone enters the information, the callsign remains in a managed state until the owner modifies the callsign information themselves.
