The main device (symbol) in the Aboril blazon is the roudle. The two main tinctures (colors) are gules and or.
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.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. 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 5A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P85. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
The Roundle is a simple circular charge that can occur in great profusion and in a variety of colours 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Roundle. Indeed, so important is this charge that special terms have been developed for each particular colour, for example the pomeis for the green roundle and the plate for the white version. There is also a visually striking version of the roundle known as a fountain, which is a circle coloured with bars wavy alternately argent and azure representing the water at the bottom of a well 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Fountain.
