Refrangibility or edge color fromation? What do you think?

Goethe dismissed Newton's idea that the continuous spectrum was a primary phenomenon. He argued that boundary or edge spectral colors are the primary phenomena in a prism and that the continuous spectrum is formed as a secondary phenomenon when the colors yellow and cyan blue overlap in the middle and mix. Prismatic colors need the boundary or border between light and darkness to appear. For Goethe colors of the spectrum can not be derived from light alone. Darkness is equally needed. Light and darkness mix at the border with another and colors arise.
