The main device (symbol) in the Branson blazon is the gyronny. The three main tinctures (colors) are sable, or and azure .
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 1. 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 2. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 3.
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” 4. 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 5. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 6.
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 7. 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” 8.
Gyronny is a very distinctive pattern covering the whole field of the shield, being a series of triangles, drawn from the edges and meeting in the centre of the shield 9. Each triangle is known as a gyron, and these sometimes appear as charges in their own right 10. Wade suggests that the use of gyrons upon a shield should be taken to denote “unity”.
