269. And a rainbow was round about the throne in aspect like an emerald, signifies the appearance of Divine truth in the heavens about the Lord. This is evident from the signification of "a rainbow in aspect like an emerald," as denoting the appearance of Divine truth in its circumference; for "a rainbow round about the throne" signifies Divine truth round about; "in aspect like" signifies appearance. The appearance was like an emerald, because it had reference to the Last Judgment; for the color of this stone is green, and "green" signifies truth obscured. Divine truth in its brightness appears either of the color of heaven, or in various colors in beautiful order like a rainbow; but when obscured it appears of the color of an emerald. The heaven that was obscured was the heaven called "the former heaven," on which judgment was to be executed, and which was about to perish (See Revelation 21:1). On this account "a rainbow round about like an emerald" is mentioned. "Rainbow" signifies Divine truth in the heavens in its order and consequently in its beauty, because there are infinite varieties of truth from good in the heavens, and when these are represented by colors, they present the aspect of a most beautiful rainbow. For this reason "a rainbow" was made the sign of the covenant after the flood (Genesis 9:12-17). (That there are infinite varieties in the heavens see in the work on Heaven and Hell 56, 405, 418, 486; and in the small work onThe Last Judgment 13; and in Arcana Coelestia 684, 690, 3744, 5598, 7236, 7833, 7836, 9002; that colors in heaven appear from the light there, and that they are modifications and variegations of the light, n. 1042, 1043, 1053, 1624, 3993, 4530, 4742, 4922; and that the colors appear various according to the varieties of the states of truth from good, and thence of intelligence and wisdom, n. 4530, 4677, 4922, 9466; that rainbows are seen in heaven, and whence and what they are, n. 1042, 1043, 1623-1625)

4530. Colours are also seen in the next life whose splendour and brilliance so surpass the richness of the colours in the world that scarcely any comparison is possible. They are products of the variegation of light and shade there. And because intelligence and wisdom from the Lord exist there which are seen as light by the eyes of angels and spirits, and at the same time inwardly enlighten their understanding, the colours there are in essence variations, or one may say, modifications, of intelligence and wisdom. The colours there with which not only the flowers are adorned, different skies painted, and different rainbows produced, but also those which are manifested in other forms, I have seen so many times that I can hardly number them. Their splendour derives from the truth which belongs to intelligence, and their brilliance from the good which belongs to wisdom, while the colours themselves are products of the brightness and the dullness of these, and so are the products of light and shade, like the colourings produced in this world. Consequently the colours which are mentioned in the Word - such as those of the precious stones in Aaron's breastplate, and on his holy vestments; those in the curtains of the tent where the Ark was; those in the foundation-stones of the New Jerusalem which are described by John in the Book of Revelation; and those mentioned elsewhere in the Word - represented aspects of intelligence and wisdom, though what each represents individually will in the Lord's Divine mercy be stated in the explanations of those parts of the Word. In general to the extent that they contain splendour and derive from the shining brightness of light the colours there are products of the truth which belongs to intelligence, and to the extent they possess brilliance and derive from the purple glow of light they are products of the good which belongs to wisdom. Those colours which owe their origin to such sources also belong to the provinces of the eyes.
