by William Mortensen Vaughan

The official threadcount from 
The Scottish Register of Tartans:

"AA12LSB4B4AA60WG4AA4GO4LG8GO4WG4GO2WG36GO2LSB4B4GO8

"Pallet:
"B=2C2C80BLUE;DB=202060DARK BLUE;GO=E8C000GOLD;G=006818GREEN;LB=2888C4LIGHT BLUE;LG=289C18LIGHT GREEN;LSB=98C8E8LIGHT SKY;AA=506494ANC AZURE;GN=406054GREEN GREY;WG=408060WTHRD GREEN;GO=BC8C00DARK GOLD;"

NOTE:

Although only one shade of gold (GO) 
is mentioned in this official threadcount,
The Scottish Register of Tartans lists 
two hexadecimal codes for GO/GOLD
in this official "pallet":

"GO=E8C000 (GOLD)"
"GO=BC8C00 (DARK GOLD)"

I used BC8C00.
