Spotted: The Seoul-based Hanwha Galleria shopping mall is using media art installed on its exterior to inform pedestrians of fine-dust levels. The feature uses red and green colour hues of to indicate the levels of pollution.

For example, if fine-dust concentration is at elevated levels, the lighting on the exterior of the Galleria will be red while showing green when levels are low. On especially bad days — when fine dust levels are 81μg/m3 or higher — KF94 certified masks will be given to customers.

The innovative lighting is part of Hanwha Galleria’s “Right! Galleria” campaign aimed at promoting a culture of eco-friendly sustainable consumption.
