The main device (symbol) in the Pride blazon is the lamprey. The two main tinctures (colors) are sable and argent.
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 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. 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 2Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
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) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G.

Croton, Quantum, London, 2013, P150, although truth be told many of the actual images are sometimes indistinguishable, being shown as a stylised, and easily recognised “trout” shape 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P137 that a child might draw. The actual name used in the coat of arms may be some play-on-words or allusion to the family name, as in the famous arms of the de Lucy family, being “Gules, three lucies or”, 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 79 this being an ancient name for the fish we call today a “pike”. It is possible that the lamprey has been used in this fashion, or it may simply relate to some fishing activity in the history of the family.
