The heart typically has a form of cardioid, the lower part of which ends in a point. The symbol is drawn with its tip down, the two lobes of the cardioid pointing upwards. Generally, the hearts are coloured red.
The first playing cards published in Europe did not have any of the suits encountered in modern French suited-decks. Latin suits (Batons, Coins, Swords and Cups) may have been adapted from card games in the Muslim world. French suits were introduced by French playing-card makers at the end of the 15th century, probably by adapting Germanic suits (Acorns, Bells, Leaves and Hearts).
French retailers produced a simpler design compared with the earlier suits, allowing easier reproduction and therefore a lower manufacturing cost. The sign of heart is taken from the Germanic suits, but has been greatly simplified..
