The four main devices (symbols) in the Cameron blazon are the bar wavy, savage, border and arm in armour. The two main tinctures (colors) are or and gules.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1. 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 2. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.3.
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 bar is a thin, horizontal stripe across the centre of the shield, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). It is also possible to place decorative edges along bars, typically these are smaller than those found on the major ordinaries like the fess and pale, but have the same design and share the same meanings. The decorative edge pattern Wavy, is a typical example of this. For obvious reasons it is associated with both water and the sea 7. Indeed, a roundel with alternating bars of azure and argent (blue and white) is known by the shorthand term fountain, representing water at the bottom of a well 8. Other colours have also been used and the result can be very pleasing to the eye.
Heraldry is a human art, by and for people and it is not surprising that people themselves are frequently depicted in arms 9. As well as the nobility themselves, we also see both the mundane, ploughmen, fishermen and reapers; and the exotic in the form of club wielding savagesand the Moorish or Saracen gentleman with his decorative wreathed turban 10.
The border, (sometimes bordure) is a band running around the edge of the shield, following the edge contours and being differently coloured, possibly holding a series of small charges placed on top of it 11. According to Wade, the bordure itself has no direct meaning, but is perhaps a container for the meaning of its colour or those additional charges placed upon it 12
