Yeah, sterile white sounds good, especially when the nefarious group thinks/believes they’re doing the right thing.  Even in my case, the canary yellow group thinks they’re doing the right thing too.  As I re-read the material (rewriting), I did notice a lot of black, however, I think the switch to canary yellow is a *WAY* better decision.

For villains, I like to use colors that seem unnatural or out of place. I once wrote a Steven Universe fanfic about a nefarious collective intelligence called the Splinter, which could infect people and control their minds. Infected persons had swirling orange specks in their eyes. I chose orange because it's not a color you ever see in human eyes, or a color that was normally associated with any of the main characters.

I really make my plots complicated.  In my case, it’s not the intention of the canary yellow group to be evil, the canary yellow simply being a close proximity to the Hufflepuff colors around the martyr that’s been chosen, and this group is being tricked/fooled into being evil toward Harry.  Bottle green is by the next group is to (incorrectly) affiliate themselves with Harry, reinforcing the fears at the core of the slander/smear campaign being waged against him.

In prior drafts, I had both groups in black (ie “dark”).  However, this pass through (of what I hope to be the FINAL draft), the canary yellow simply evolved, and I realized it was more effective than the black had been.  I applied the same logic to the next group, and so they’re going to be in robes of bottle green, to match Harry’s eyes.
