The two main devices (symbols) in the Ferm blazon are the lion’s head and fesse. The three main tinctures (colors) are gules, or and azure .
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P76-77.
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 7Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
There can be no animal more clearly associated with Heraldry than the lion, majestic King of the Beasts.9Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 64 The head of the lion also appears alone on many coats of arms, but its use in this form is largely to enable a clear difference from similar arms that use the complete animal, and its significance should be taken to be the same as the lion entire, being a symbol of “deathless courage”. 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P59
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 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fesse. 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”.
