The regiments of foot were provided with red coats. Red was chosen because uniforms were purchased competitively from the lowest bidder, and Venetian red was the least expensive dye. Those used by the various regiments were distinguished by differently coloured linings, which showed at the collar and ends of the sleeves, and generally matched the colours of the regimental and company standards. In time, they became the official "facing" colour. On some occasions, regiments were referred to, for example, as the "blue" regiment or the "white" regiment from these colours, though in formal correspondence they were referred to by the name of their colonel. Each company had its own standard, square. The colonel's company's standard was plain, the lieutenant colonel's had a cross of Saint George in the upper corner nearest the staff, the major's had a "flame" issuing from the cross, and the captains' standards had increasing numbers of heraldic decorations, such as roundels or crosses to indicate their seniority.
