The freak flag is missing INDIGO, the color associated with the third eye chakra. Because it was so expensive to extract indigo dye from the murex snail, the color came to be associated with royalty and the elite. It wasn't until the middle of the 19th century that German scientists were able to create synthetic indigo (mauve) from coal tar. This discovery kickstarted the German chemical industry, led to the creation of IG Farben, and would eventually allow the nazis to wage a world war without an empires worth of natural resources at their disposal. God's rainbow is full spectrum-red orange yellow green blue indigo and violet (plus a whole bunch of colors we can't see yet). The devils rainbow has six.
