White is not a colour, but white is all of the colours combined. White is the light before refraction, but nothing without another colour to provide contrast. Equality is contradiction.
White is also tellingly absent from the official colours of the city of Paris, which display just the red and blue. White the colour of the royal family and the Catholic church, not the colour of the people. White a colour that nevertheless seems to be everywhere in the city - until you look more closely. It's a pale city, not a white city, but can any city ever be truly white? Wipe it clean, but time, dust and fingerprints soon bring the colours back.
