Shades of Grey: The Road to High Saffron, Paperback

Welcome to Chromatacia, where the societal hierarchy is strictly regulated by one's limited color perception. And Eddie Russet wants to move up. But his plans to leverage his better-than-average red perception and marry into a powerful family are quickly upended. Juggling inviolable rules, sneaky Yellows, and a risky friendship with an intriguing Grey named Jane who shows Eddie that the apparent peace of his world is as much an illusion as color itself, Eddie finds he must reckon with the cruel regime behind this gaily painted facade.
