Chromatic

Chromatic is the oldest rainbow in the collection. Added in Era 1 as an Exalted aura at 1 in 20,000,000, it comes to about 2,000,000 rolls at 10x luck, and ENDAWERKZ and justr_ndx are credited. The in-game line is a shout about unstoppable beats, which tells you what it is about: everything on screen follows the music.

Two color-changing stars spin counterclockwise around the player, forming a thin ring of light, each with a pulse behind it. The title above the player pulses too. Outside that comes a ring of spikes that works like an audio visualizer, and three rainbow fans or wings spin clockwise behind. The player floats in a transcending idle pose that the wiki likens to Galaxy's. Beams of light and sparkles drift outward at different speeds, and colors, rays, trails and the aura tag all correspond to the track. The family has four more members: Chromatic : Exotic (removed), Genesis, Hyper and the April Fools skin Kromat1k.
