As the film progresses and the relationship solidifies, the blue hair fades. When Adèle visits Emma’s art exhibition in the film’s final act, Emma’s hair is blonde. The blue has been stripped away, symbolizing the end of the mystique. The warmth has cooled. The final scene, where Adèle leaves the gallery and turns a corner, signifies her acceptance of reality. She no longer chases the "warm blue" ideal; she steps into the grey uncertainty of adulthood.
