Blue is a deep reflection on melancholy and loneliness. An image that evokes a feeling of endless space, symbolising immense possibilities, but at the same time emphasising the loneliness and incomprehensibility of the universe.A face covered with a mask serves as a symbol of hidden emotions and imperfection. The element of the mask also expresses the idea that the inner world of a person often remains incomprehensible and impenetrable to others like the endless space.
