Everything's Better with Rainbows, right? They show a spectrum of visible light, and you see colours at different positions. But what if instead of being given colour variation over distance, you are given colour variation over time? This seems almost like glowing, except with the wavelength varying along with (or maybe instead of) the intensity... in other words, a colour cycling glow. EDIT: I am considering broadening this to glowing in general, including both wavelength variation and intensity variation, as we do not seem to have a trope about glowing in general, just contexts it is associated with. Any input on this idea?
