What does a task's color mean?
From Planfix
A task name's color shows the task's status or its state. The following colors are designated for specific task states:
- Red — task overdue.
- Green — task has the status Ready for review and is awaiting result checking by the assigner.
- Gray — task is either Postponed or Canceled.
- Gray+strikethrough — task is Completed.
- Purple — task is a template
- Orange — the task becomes this color when its start or due date falls on the assignee's non-working day during a move. This reserved color indicates that the Assignee did not accept the Task on time because the start date fell on the assignee's day off.
- Black — the Task is a Draft.
The remaining colors for tasks can be assigned to statuses in the Account management — Processes — Status sets section.
