Black Watch of Canada, vehicle unit Markings ww2

[Aidan]

Found the insignia's that I wanted for the Black Watch on a vehicle. Green background square with the Div #60 in white I belive that would be on the Right fender and on the left fender would be Royal Blue square with a Gold leaf. Now what would be the size of the Green Square and Royal Blue Square. and would yellow substitute Gold for the golden leaf? also what Shade of a Green would they have used. Thanks Aidan
