Note: In order to be able to access the administration panel and manage colors you need to be a system admin.
In OpenProject you can define the colors for different work package types (phases or milestones) displayed in the timeline. The spectrum of the colors available can be managed through the administration panel. To do that navigate to Administration and select Colors from the menu on the left side. You will see the list of all already defined colors. If no color has been defined yet, the list will be empty.
