Gules is the most widely used heraldic tincture. Through the sixteenth century, nearly half of all noble [[coat of arms|coats of arms]] in [[Polish heraldry|Poland]] had a field gules with one or more [[argent]] charges on them.{{citation needed|date=April 2019}}

Examples of coats of arms consisting of purely a red shield (blazoned ''gules plain'') include those of the [[Albret|d'Albret]] family, the Rossi family, the Swiss [[canton of Schwyz]] (prior to 1815), and the old coats of arms of the cities of [[Nîmes]] and [[Montpellier]].
