The redness, also, of the blood is from the correspondence of the heart and the blood with love and its affection; for in the spiritual world there are all kinds of colors, of which red and white are the fundamental, the rest deriving their varieties from these and from their opposites, which are a dusky fire color and black. Red there corresponds to love, and white to wisdom. Red corresponds to love because it originates in the fire of the spiritual sun, and white corresponds to wisdom because it originates in the light of that sun. And because there is a correspondence of love with the heart, the blood must needs be red, and reveal its origin. For this reason in the heavens where love to the Lord reigns the light is flame-colored, and the angels there are clothed in purple garments; and in the heavens where wisdom reigns the light is white, and the angels there are clothed in white linen garments.
