According to “The Language of Stained Glass”
at Armstrong Browning Library at Baylor University:
When Dante spoke of the Seraphim — the first of the nine choirs of Angels —
the color that “glows” was the pure orange vermilion
which his fellow citizens and brothers-in-spirit
(the painters, illuminators, and glassmen) knew as red.
So, it may be said that pure red is the color of divine love,
the Holy Spirit, courage, self-sacrifice, martyrdom,
and all the warm impulses that belong to the great-hearted everywhere.

Our world is painted with enormous beauty by the 7 colors of the rainbow, and those seven basic hues yield thousands of other shades that also characterize the world in which we live. Not surprising because color figures into the 7 days of Creation’s origins. For example, on day 1 light was created and the color white symbolizes God and His love. On day 2 God created expanses to separate water from water. Both the heavens and water are blue. On day 3 green plants were created. On day 4 lights were placed in the heavens, and the greater light that governs the day is yellow. On day 5 fish and birds and great sea monsters were created, and it has been said that the “sea monsters, such as whales and sharks, symbolize a giant, such as Baal(one of the seven princes of hell and a pagan idol mentioned widely in the Old Testament), who is evil” and symbolized by the color orange. On day 6 man and animals were created. The blood that courses through their veins is red, the name Adam means red, and the first color used by man as seen in cave drawings is red. The 7th day was sanctified by God who is symbolized by the color white, and purple was the color of the robe placed on Jesus before His crucifixion.
And God said, “This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. -Genesis 9:12-13
