As for the origin of the red color (in the Slovak and in the Hungarian coat of arms), the coat of arms has often had the red color as an almost inseparable attendant of the double cross in the coats of many Hungarian and Slovak towns since the Middle Ages. Also, the coat of arms of Béla III. is thought to have had red background. In general, red background color was used frequently for coats of arms in the late 12th and early 13th century in central Europe. One of the modern interpretations of the color is that it represents the bloody lining and symbolizes the Slovak 'martyrdom' during the time of Magyarisation (19th century).
