Bright geometric shapes make the graffiti work of Kenyan artist Wise Two really stand out. Michael Kaloki tracks how his bold style is evolving as he travels to Mexico where. he says, street art is more widely accepted than in Nairobi, a city where he tends to paint murals in densely populated districts like Kibera and Jericho. On this trip to Mexico, Wise Two has started using a more varied colour palette and not just the traditional primary colours of Maasai masks he was known for. He is also using gold leaf on smaller canvases and abstract shapes on a tricky commission to paint cylindrical air-conditioning vents, not the usual flat surface which graffiti artists decorate.
