Labels are colored tags on tasks. They are not columns — use lists for workflow stages and labels for type, priority, or area.
On a task
Open the task → Labels → +. Check labels to apply. You can create/save colors from that picker (labels/save) and remove unused ones (labels/delete/{id}).
Several labels can sit on one task.
Dashboard
The project dashboard charts tasks per label, so a small, stable set of names works better than dozens of one-off tags.
Admin list
If your install exposes Settings → Labels, you can search and edit the catalog (Labels/Index). Many teams only ever create labels from the task panel.
