Nine additional hatchings, published by Marcus Vulson de la Colombière in 1639, were intended to represent other colours, although none of them correspond with regular heraldic tinctures, and they have never been used in British armory. A combination of vertical lines with diagonal lines running from dexter chief to sinister base represents brown; blood red is represented by vertical lines combined with diagonal lines running from sinister chief to dexter base; earth-colour by horizontal and vertical lines combined with diagonal lines running from dexter chief to sinister base; iron-grey by diagonal lines running in each direction (the same as sanguine in Petra Sancta's system); water-colour by broken horizontal lines; flesh-colour by broken vertical lines; ashen-grey by a combination of broken horizontal and broken diagonal lines; orange by broken vertical lines interspersed with dots; and the colour of nature by zig-zag lines running from dexter chief to sinister base.
