After the Colour Drain, everybody on Earth sees the world in black and white. That is, everyone except the ones known as Elementals. After going her whole life seeing in monochrome, a young English woman wakes up one day with the ability to see only one colour. Before she can understand the gravity of her situation, a foreign Elemental sent to kill her finds charm and adorability in her confusion and takes her on his journey to stop the Salvaging, bringing more colour to her life as he helps her figure out what she is.
