Italian artist Francesco Camillo Giogino, also known as Millo (previously), is known for his site-specific street murals that adorn buildings with a cast of curious characters painted in primarily black and white. Millo adds subtle color to his works, highlighting hearts, thermometers, and vegetation with shades of red and green. His most recent mural (seen above) is titled In Bloom and was painted in Milan. You can see more of his murals on his website, and on Facebook.
