|The MacKinnon tartan now generally available and
approved by the chief, has altered its appearance over the
years, and returned to the form of the earliest example.
The collection of certified tartans made by the Highland
Society of London (c.1816) includes a specimen signed by
the Mackinnon in which the purple stripes are a light
shade of azure, a minor change that is mirrored in other
tartans, notably the Royal Stewart.
