Although the Ancient Campbell tartan is lighter in color than the Black Watch tartan, they are both Black Watch tartans, which is a Campbell regiment, raised by the Duke of Argyll in 1739. It is thought that the Black Watch tartan may well have been adopted as the clan's tartan because so many members of the clan were already wearing it, owing to their service in the regiment.
The Black Watch modern tartan is usually made in darker shades of green and blue, while Ancient Campbell is made in lighter, brighter shades. Some Campbells wear the lighter Ancient Campbell for day wear and the darker Black Watch for evening and formal wear--the important point being that they are the same tartan.
