English: The "Prince Charles Edward Stuart" tartan, a variant of royal Stewart with a smaller proportion of red, and differing widths of thin over-checks. This version is in the palette used by 72nd Seaforth (Highland) Regiment of Foot, Duke of Albany's Own, for their unform trews (1823–1881), with a comparatively pale blue and green, as shown in period art. Identified in surviving cloth samples from the mid-18th century (before the regiment), it is one of the oldest setts in continuous production [1]. For clan and fashion use, a "modern" palette with usual saturated green and blue is typically used.

This version of the image is exactly full-sett, and is tileable horizontally and vertically. Scottish Register of Tartans notes on this sett: "The Prince Charles Edward sett is essentially the Royal Stewart but for the much reduced red square. Wilsons of Bannockburn included it in their 1819 Key Pattern Book, the details indicate that they had been weaving it for a number of years and it seems likely that the naming was theirs. Later in the 1800s it was worn as the regimental tartan by the 72nd Duke of Albany’s Own. In their 1850 book 'The Clan and Family Tartans of Scotland' W and A Smith of Mauchline wrote: 'Our reason for giving this, is, that it is copied from the identical coat worn by the young Chevalier when in this country, and which is in the possession of a gentleman of high respectability in Edinburgh, who has distinguished himself by a work upon the "Highlanders of Scotland"'. That author was no doubt W. F. Skene whose book of that name was published in 1836. However, the Smiths' story is apocryphal; the coat was examined in 2019 and found to date to the early 19th century."

This is an asymmetical (non-mirroring) sett. SRT-provided thread count (with a non-standard colour code normalized to a standard tartan colour), in "..." notation: ...R56 A16 K24 Y4 K8 W8 K8 OG48 R24 K8 R8 W4 R8 K8 R24 OG48 K8 W8 K8 Y4 K24 A16... (where A = azure, OG = olive green).
