Toward Ecosophy

Color theorists in the English-speaking world have always been left floundering by Isaac Newton's insistence that there had to be seven colors in the spectrum. If you have a six-color wheel, as Goethe demonstrated, you're fine -- everything works out -- but indigo is neither a primary nor a secondary color, it's one of six tertiary colors, and including it but not the other five tertiary colors makes a mess of the whole scheme. I'm pretty sure Heindel stuck it in the center because he thought he had to do something with it.
