380. The fact that the blood is red is owing also to the correspondence of the heart and blood with love and its affections. For the spiritual world has in it colors of every kind. The colors red and white are the fundamental ones, and the rest take their variations from them and from their opposites, which are a dark fiery color and black. The color red there corresponds to love, and the color white corresponds to wisdom. The color red corresponds to love for the reason that it takes its origin from the fire of the sun in the spiritual world; and the color white corresponds to wisdom for the reason that it takes its origin from the light of the sun there. Because, then, there is a correspondence of love with the heart, therefore the blood cannot but be red and attest its origin. It is in consequence of this that in the heavens where love toward the Lord reigns, the light is a flaming one, and the angels there are clad in purple garments; and in the heavens where wisdom reigns, the light is bright white, and the angels there are clad in garments of white linen.
