I know there was a wikipedia article on it, but I can't find it now. During my search, I came across the same query on reddit, but the post body had been deleted.
Wish I could find it now. I remember thinking when I read about it that the color/pigment was within the skillset of the home/hobbyist chemist.
Posting in case you find that info you had before about that pigment because it sounds wild
Look into Dicyanin. I think that’s what you’re searching for.
