NEW YORK -- Cuban-born artist Carmen Herrera, whose radiant color and geometric paintings were overlooked for decades before the art world took notice, has died. She was 106.Artist Antonio Bechara told The New York Times that Herrera had died at her Manhattan home Saturday.Fame finally came at age 89, when Herrera sold her first painting in 2004.It may have taken 60 years for Herrera to be discovered, but today her paintings — minimalist compositions of straight lines, form and color — are found in permanent collections of major museums including the Whitney Museum of American Art and the Museum of Modern Art in New York and the Tate Modern in London.“The core to Carmen Herrera’s painting is a drive for formal simplicity and a striking sense of color,” according to the London-based Lisson Gallery.
