Hermelindo Fiaminghi (1920–2004) was a Brazilian painter, graphic designer, lithographer, and educator, renowned for his contributions to geometric abstraction and color theory. Born in São Paulo to Italian immigrant parents, he studied at the Liceu de Artes e Ofícios de São Paulo from 1936 to 1941, learning under artists like Lothar Charoux and Waldemar da Costa. Initially working in lithography and graphic design, Fiaminghi founded Graphstudio in 1946 and later served as an art director in advertising. In the early 1950s, he transitioned to abstract art, joining the Grupo Ruptura, a collective pivotal to Brazil's Concrete Art movement. His early works emphasized geometric forms and limited color palettes, creating visual rhythms. Between 1959 and 1966, he studied with Alfredo Volpi, refining his use of tempera and exploring color transparency. In the 1960s, Fiaminghi developed the concept of "Corluz" (Color-Light), focusing on the interplay of color and light, often utilizing reticulated patterns inspired by graphic design. Later in his career, his style evolved to include more gestural brushwork, as seen in his "Despaisagens" series. Fiaminghi's work has been exhibited in major institutions, including the Museum of Modern Art in New York, and he remains a significant figure in Brazilian modern art.
