Spinner was on odd one for color and ability. His Gecko quirk isn't too notable, only giving him a lizard-like appearance and letting him attach himself to stuff like a gecko. With that, Spinner does tend to use traditional weapons when he fights, and I remembered his sword made of bladed weapons from the forest training arc. That was the inspiration for his ability. As for color, well the ability was naturally white. I've justified the colors of other characters solely based on the ability I gave them, but I feel Spinner is fine as white. Spinner doesn't give me vibes from any other color, but trying to keep Stain's code in practice makes me think white (his belief and faith in the code, not Stain's beliefs).
