Nù Barreto’s practice draws attention to the social disparities endemic to the African continent. Using dry mediums, collage, reconstituted materials and new media, Barreto’s work has a strong symbolism expressed through form, color and patterns. He frequently makes use of the funguli colour, a grey, ashen tone often used in reference to impoverished individuals in Guinea-Bissau. Barreto began using this colour to subvert its negative connotation and highlight the reality of the socially and economically dispossessed.
He has participated in solo and group exhibitions across the five continents including the Dak’Art – Biennale de l’Art African Contemporain (2006), and the traveling exhibition Lights of Africa (2016). His works are included in the collections of the PLMJ Foundation, Lisbon and the Pro-justitia Foundation of Porto and Macau, Victoria Mucane Museum of Brasilia and the West African Monetary Union Collection.
