Red

Red is a color that in history is linked to power, to vengeance, to slaughter, to love. Since red is the color of blood, it has historically been associated with sacrifice, danger and courage. Modern surveys in Europe and the United States show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love and joy. In China, India and many other Asian countries it is the color of symbolizing happiness and good fortune. Red is associated with the warrior caste in India and Rome, and to the warrior Goddess Sekhmet in Egypt. Some of Sekhmet’s titles were “Powerful of Heart,” “The Scarlet Lady,” “Avenger of Wrongs,” “Lady of Flame,” “The One Before Whom Evil Trembles,” “Eye of Ra,” and “Lady of Slaughter.” 
Red was considered a martial colour (quite literally, Mars was clad in red, and he was as red as was Ares), divine and awe-inspiring. One of Martials epigrams (14, CXXIX) mentions a soldiers preference for the colour red: Roma magis fuscis vestitur, Gallia rufis, Et placet hic pueris militibusque colos. Before anything, let us take the color red. This color, which has become the emblem of subversion, previously, as purple, had recurring connection with the regal and imperial function—connection not unrelated to the sacred character recognized in it. The tradition can carry us as far back as classical antiquity, where this color, in its correspondence with fire conceived as the highest of all the elements (that which, according to the Ancients, was the substance of the highest heaven, for which this heaven was called empyrean51 ), is associated also with triumphal symbolism. In the Roman rite of “triumph,” whose character was more religious than military, the emperor, the victor, not only dressed in purple, but originally dyed himself in the same color, so as to represent Jove, the king of the gods, who was thought to have acted through the emperor’s person, and thus to be the true artificer of the victory. It is superfluous to cite examples of successive traditions which regarded red as the color of regality: in Catholicism itself the “purple” is sign of the “princes of the Church.”52 Here and now we see this same color degraded in the red Marxist flag and in the red star of the Soviets.
