tile roofs, and simple, peaked wooden roofs, every structure had been blackened to some degree. the city wall, was blackened by a patina of soot. structures were generally darkest at the top, where the ash gathered, but rainwaters and evening condensations had carried the stains over ledges and down walls. like paint running down a canvas, the darkness seemed to creep down the sides of buildings in an uneven gradient. by ismail inceoglu, peter mohrbacher, trending on artstation
