It is only the "Aljean" if the darkest color is another color blue. If not, it is 42nd Regiment with a hinky thread count. The 42nd sett does not include what D.C. Stewart termed the "Black Watch" motif.

As for the Stewart / Stuart in the Government color way: Almost all Tartanology scholars, incl. D.C. Stewart, James D. Scarlett, P.E. MacDonald, M.A.C. Newsome, et al recognize the "Government Regiment" sett foundation as blue / black / green.
