The two main devices (symbols) in the Newburgh blazon are the bendy and lozengy. The two main tinctures (colors) are azure and or.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
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” 3The 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 4Understanding Signs & Symbols – Heraldry, S. Oliver & G.

Knowing that the bend is a diagonal stripe of colour, we can easily conclude that bendy is the variant whereby the whole of the shield is covered with diagonal stripes of alternating colours, usually around 4 or 5 of each colour. 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bend We should not assign any particular significance to the choice of this pattern, but rather more to the colours they are composed of.
Anyone who has seen a typical Jester’s or Harlequin’s outfit has seen the treatment known as lozengy – a pattern of interlocking diamonds of two different colours 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Lozengy. It normally covers the whole field of the shield, as in the ancient arms of FITZ-WILLIAM, Lozengy, argent and gules, a striking example of the form.
