The four main devices (symbols) in the Joy blazon are the guttee deau, leaf, rose and lion. The three main tinctures (colors) are vert, gules and or .
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” 1. 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 2. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”4. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 5. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.6.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.7. 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 8. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.9.
The gutte or goutte is an elongated tear-drop shape with wavy sides and usually appears in large number spread evenly across the field. 10 Some frequently do they occur that special names have arisen for the various colours, guttee d’eau being argent (or white) for its obvious resemblence to drops of water.
Amongst the natural objects depicted on a coat of arms, trees feature frequently, either in whole or as individual branches and leaves. 11. Sometimes the species or the part of tree was chosen as an allusion to the name of the bearer, as in Argent three tree stumps (also known as stocks) sable” for Blackstock 12 Trees of course had long been venerated and its use in a coat of arms may have represented some association with the god Thor 13
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 14. The rose is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It has long been present in English heraldry, and as a badge and symbol played an enormous in English history throughout the conflict between rival dynasties known as the War of the Roses. In addition to these familial uses, Wade suggests that red roses signify “beauty and grace” and the white represents “love and faith”. 15
