The main device (symbol) in the Dunsford blazon is the beehive. The three main tinctures (colors) are sable, argent and vert .
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.
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) 4. In a sketch or drawing it is represented by plain, unmarked paper 5.
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 6. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 7. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 8. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
