The two main devices (symbols) in the Britee blazon are the escallop and fesse. The three main tinctures (colors) are argent, sable and or .
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 1. In a sketch or drawing it is represented by plain, unmarked paper 2.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 3. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 4. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 5.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.6. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 7. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.8.
The escallopoccurs often in arms, represented as the outside of the shell, sometimes “fluted” of a different colour 9. It has been part of heraldic tradition almost from the beginning of the art, Henry III of England awarded Gules, 3 escallopes argent to Herbert de CHAMBERLEYNE in the 13th century, and it is present in the heraldry of almost all countries 10. It is believed that they were adopted as badges of those going to the Holy Land and can be found in the arms of many a crusading family. Hence Wade’s suggested association of the scallop with those that “complete long journeys to far countries” 11.
The fesse (also found as fess) is one of the major ordinaries to found in heraldry, being a bold, broad, horizontal band across the centre of the shield. It may originally have arisen from the planks of which a wooden shield can be constructed, the centremost plank being painted a different colour 12. It is instantly recognisable as a symbol, for example the arms of COLEVILLE granted during the reign of Hery III are simply or, a fesse gules. With this clear association with the construction of the shield itself, Wade believes that the fesse can be taken to be associated with the military, as a “girdle of honour”.
