The color of sky is one of the most intuitional signals to reflect the situation of air environment. We visualized the sky color of 2015 Beijing, compared them with PM2.5 value of the whole year. The connection can be seen directly in the graph. Moreover, the air condition is better in summer than winter, since the range of typical blue days in summer is wider than winter.
