The two main devices (symbols) in the Kingsman blazon are the per pale and saltire. The two main tinctures (colors) are argent and azure.
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) 1Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
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” 3Boutell’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 4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
The background of the shield can be divided into two potrtions in a variety of ways, and each portion treated differently. In the heraldry of continental Europe there is a tendency to use these areas to combine two different designs, but in British and Scottish heraldry the preference is to treat the divided field as a single decorative element with other features placed as normal. Whatever tradition is followed, one of the most common divisions is per pale, a simple separation along a vertical line. Wade assigns no particular meaning to the use of this division, but suggests that they simply arose from the multi-coloured garments typically worn at the time of the birth of heraldry. 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P56
The saltire is one the major ordinaries, large charges that occupy the whole of the field 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Saltire. Arguably one of the best uses of this device is that of the St. Andrews Cross, a white saltire on a blue background found on the Scottish flag. The saltire is obviously closely related to the Cross, and Wade in his work on Heraldic Symbology suggests additionally that it alludes to “Resolution”, whilst Guillim, an even more ancient writer, somewhat fancifully argues that it is awarded to those who have succesfully scaled the walls of towns! 7A Display of Heraldry, J. Guillim, Blome, London, 1679, P63
