The main device (symbol) in the Linda blazon is the tree. The two main tinctures (colors) are gules and or.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).3
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4. 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 5. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.6.
Amongst the natural objects depicted on a coat of arms, trees feature frequently, either in whole or as individual branches and leaves. 7. 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 8 Trees of course had long been venerated and its use in a coat of arms may have represented some association with the god Thor 9
