Roy G. Biv isn't where rainbows are exploited. God created the rainbow. Nearly all of the rainbows lack Indigo; our connection to the ether. Just six colors in the exploited rainbows. Biblically 6 means incomplete, 7 is complete. Almost every rainbow used to promote deviant practices omits Indigo, leaving a 6 color praise to the Wicked one and demons. Typically human.
For those that don't know, Roy G. Biv. His name is made from the colors of the rainbow
