A group of designers from South Korea
found a way to fight those gloomy days when it just wouldn’t stop
raining. Together with Pantone they brought back the colours to Seoul by
creating huge vibrant paintings on the streets which appear when it’s
raining.
Their project is titled “Project
Monsoon” and, as the name suggests, was created for the annual monsoon
season when it rains for as long as 3 weeks. The artists used
special hydrochromatic paint, which stays invisible until it gets wet. (Source)
