Coloratura, by Maryland artist Mary Ann Mears, is located at Southern Avenue station on the Green Line in Prince George's County, Maryland. Coloratura consists of suspended and high-relief wall sculptures. The piece was impeccably crafted by Maryland boat builders, Chesapeake Rigging, using painted metal and stainless steel. The artist uses her trademark brilliant colors, rhythmic patterns and bold forms to create a work of art that is animated, colorful and inspiring.
