For the past decade, artist Seb Toussaint has travelled to some of the poorest parts of the world to paint brightly coloured frescoes on the walls of downtrodden neighbourhoods.
Dressed in shorts and a T-shirt, the 35-year-old French-British artist, who always paints an inspiring word at the heart of his work, is tackling a piece called "Future" in a dusty slum on the outskirts of Mauritania's capital Nouakchott.
"The goal is to paint the words of those who don't have a voice," he says.
He and two travel companions have daubed the sides of a sheet metal shack with a mural of geometric and undulating shapes in white, blue and baby pink.
As they work, children play in the dirt paths, rolling a tyre or kicking a ball between makeshift homes, as curious women in colourful veils mill around.
Zaatar is a hodgepodge extension of the capital, where fishermen, construction workers, carpenters and casual workers have made their homes.
The soil is too salt-laden to be cultivated, and there is little greenery aside from two ailing acacia trees.
Bringing colour to the poor
Since 2013, Toussaint has painted walls of cement, wood, and corrugated iron with words in different languages and alphabets as part of his project, which he calls "Share the Word".
There was "Humanity" in the Palestinian Territories, "Change" in Nepal, and "Freedom" in Iraq.
He earns a living painting murals in Europe and saves up to finance about two trips a year to spend a month in a slum or refugee camp, where he offers his services to residents.
The homeowner will decide what word he wants highlighted in the mural.
Toussaint started his career painting "tifos" - vibrant choreographed displays held up by fans at football matches.
He decided to dedicate himself to bringing "colour to an environment where there is very little," after being exposed to the harsh realities some people face when travelling the world on his bicycle a decade ago.
When he arrived in Zaatar in early January, "we played football with the kids. I explained in broken Arabic that the goal was to paint houses. One person said: I would like you to paint my house."
"We have never had anyone turn us down," he said.
However, there is often an initial reluctance.
"We had our suspicions about their presence, but we quickly realised these guys had good intentions," said fisherman Amar Mohamed Mahmoud, 52.
"They do a good job that brightens up the neighbourhood."
Peace and love
Mahmoud got a rare animal painting, "The Camel," in shades of blue and fawn, in honour of the animal which plays an important role in Mauritanian society.
He has painted eight murals in the neighbourhood, among them "Mum", "Youth", and "Friends", whose colours dazzle in the sun-scorched neighbourhood.
He estimates he has painted 222 word murals around the world, with a general fondness for the themes "Peace" and "Love".
Some of his works last for years, while others are fleeting. Several murals disappeared when a migrant camp in Calais in northern France was dismantled.
The murals also become a backdrop for local music artists to shoot videos, he says. Once, in Nepal, one of his painted walls was used as a backdrop for a fashion shoot. - AFP
