Gules is the most widely used heraldic tincture. Through the sixteenth century, nearly half of all noble coats of arms in Poland had a field gules with one or more argent charges on them.
Examples of coats of arms consisting of purely a red shield (blazoned gules plain) include those of the 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.
