|The structure of the MacNab is identical with that of the
Black Watch; but, by a translation of colours, the most
subdued of tartans becomes one of the most striking.
D.C.Stewart suggests looking at the pattern through a
green filter to see the effect. James Logan recorded this
pattern in his book, 'The Scottish Gael' in 1831, despite
receiving a different sett from the largest weaving
company of the time, William Wilson and Company,
Bannockburn. Wilson's MacNab survives as an alternative
tartan for the clan.
