Hello. I stumbled upon your question while doing research for a blog I am writing, and wanted to interject the following: What you have seen, the double rainbow, is the most beautiful of Yah's signs. The rainbow is the sign of the everlasting covenant between Yahweh-Elohim [God] and "every living creature of all flesh that is on the earth" [Genesis 9:16], the covenant of everlasting life. That is why when viewed in its fullness, only possible from the air -- "God's point of view", remember -- it is an unbroken circle, representing our eternal destiny [LIFE], and here is the exciting part: the second rainbow which you witnessed is His promise to you, Binghi, His promise that you (and every living creature) have a Soul Mate [Isaiah 34:16], the very point of the story of "Adam and Eve". You see, the second rainbow (red to purple) is the perfect "opposite" of the first (purple to red), the mysterious 'wheel within the wheel' spoken of by every religious tradition. Though I have not yet written about the double rainbow on my blog, it is coming, next. Take a look, at: http://thepresenttruth.blogspot.com
Have a beautiful day, hopefully, one with a double rainbow - the circle of life!
