The Pantone Colour Institute announced the Classic Blue as the Colour of the Year for 2020. However, this colour reminds us of a bigger problem: the global issue of air pollution. Since carbon emissions in urban centres have increased dramatically, air pollution affects our lives in a number of ways. Not only painting our blue sky to smokey grey – but altering the whole ecosystem’s basic functions, too. The posters are created in a way that they are actually able to absorb pollution from the air.
