A group of South Korean designers have found a way to deal with gloomy cloudy days: they painted the roads in Seoul so that the images are visible only in the rain.
The Monsoon project was timed to coincide with the monsoon rainy season in South Korea — at this time it rains there for three weeks. The artists used a special hydrochromatic paint — it remains invisible until the surface becomes wet.
A group of designers from South Korea has found a way to brighten up the gloomy days when it rains incessantly. On the streets of Seoul, huge bright pictures were painted with special paints, which appear in bad weather.
The designers called their initiative the "Monsoon Project", since during the annual monsoon season, rain in these parts may not stop for up to three weeks. The artists used special hydrochromatic paints, which "manifest" only at high humidity.
Now residents of the Korean capital are "looking forward to the rainy season."
