When It Rains, It Pours Colorful Street Art In This City

Invisible art before the rain.

Monsoon season in Seoul, South Korea, can be pretty intense. It usually lasts three weeks with continuous rain, and that's no fun.

Unlike previous monsoon seasons, residents of Seoul finally have something to look forward in 2015 — street art. However, there's a bit of a catch when it comes to this street art.


The street art is only noticeable when it rains.

That's because the street art was created with a special type of paint that remains invisible until it gets wet.

"We painted the streets of Seoul with hydrochromic paint — a special formula which changes from transparent to opaque when it gets wet," local artist Yoonshin Kim wrote.

Paint company Pantone assisted the artists and provided the hydrochromic paint.

Their collaboration is called "Project Monsoon."

The artists wrote that they were "inspired by South Korea's culture of emphasizing the importance of the flow of rivers, the paintings utilize Korea's topographical features that create a flow and puddle of rain water in every street to fill the streets with color and life."

Before monsoon season, people can see a preview of the art through digital billboards around Seoul. There is also an online gallery of the art.

The before-and-after rainfall photos are simply breathtaking.
