l liked it when the rings were just designed by Oa or Qward scientists and engineers. The color was a side effect and having reactions controlled or aborted by wavelength as compared to the human perceptual construct of color made some sense. Such reactions happen in nature. The emotion was stupid and suspending disbelief is ok but we all know specific scientific things and this one was stupid. Yeah, most powers are stupid but being blatant (as in Earth was the center of life) demonstrates the failure of modern education (as least for these writers). The basic intro science curriculum in college should smack them in the head.
