Shield Spirit

We've written about art that appears in the rain before, but this mural in Seoul, South Korea takes hidden artwork to a new level with vibrant color. With the help of Pantone, a group of designers painted a sneaky mural on the street that only becomes visible when it rains. Monsoon season is a dreary time in South Korea, but the new artwork gives the street a pop of color. 

Called Project Monsoon, the art is inspired by South Korea's culture and topographical features. Bright blue ponds with turtles and fish have been painted with hydrochromic paint, a special formula that turns from transparent to opaque when wet. To get people excited about the project, augmented reality billboards have been installed to give pedestrians a sneak peek at the artwork to come in the rainy season. 

The project has already received some acclaim, winning the Black Pencil and a Yellow Pencil at the 2015 A&AD New Blood awards.
