The story peripherally involves a corporation named Eight Colors, but also includes a plot about people living underground, viewing the surface through prisms and periscopes. Near the end the protagonist takes a group of people to the underground community, where they are psychoanalyzed, and their emotions are encoded on shifting color badges they wear on their shirts or sleeves, i.e., literally wearing their feelings on their sleeves.

  • I don't recall the coporation, but Prodigal Sun by Philip E.High has an underground world. It's not their emotions on their sleeves though, but their psychological profile. So if someone is dishonest, everyone knows to be careful around him. One girl is promiscuous, and the man who is attracted to her is shocked by her symbols. – sueelleker Mar 21 '18 at 10:16
