It looks Photoshopped but this city is really a beautiful violet city. It is located in Paris. I think the picture was taken when the sun is about to fall and the sky cast a violet or indigo color that has been reflected by the white walls here in Paris. Whatever the reason for its color, I can just say that I am so amazed on this photography.
I almost forgot to say that the structure at the middle is called "Arc de Triomphe".
