380. That the blood is red is also on account of the correspondence of the heart and the blood with love and its affections; for in the spiritual world there are colours of every kind. Red and white are the fundamental, and the rest derive their varieties from these and their opposites, which are a smoky fire shade and black. Red there corresponds to love, and white to wisdom. Red corresponds to love because it originates from the fire of the Sun there, and white corresponds to wisdom because it originates from the light of the same Sun; and because there is a correspondence of love with the heart, the blood cannot but be red, and indicate its origin. Hence it is that in the heavens, where love to the Lord reigns, light is the colour of flame, and the angels are clothed in purple garments; and in the heavens where wisdom reigns, the light is shining white, and the angels are clothed in white garments of fine linen.
