Facing colour
A facing colour is a common European uniform military tailoring technique where the inside lining of a standard military jacket, coat or tunic visible to the observer, is of a different colour to that of the garment itself. The jacket lining evolved to be of different coloured material, then of specific hues. Accordingly when the material was turned back on itself: the cuffs, lapels and tails of the jacket exposed the contrasting colours of the lining or facings, enabling ready visual distinction of different units: regiments, divisions or battalions each with their own specific and prominent colours. While a popular practice in 18th century armies, the use of facings was especially observed and elaborated on during the Napoleonic Wars.
