Rothko largely abandoned conventional titles in 1947, sometimes resorting to numbers or colors in order to distinguish one work from another. He also resisted explaining the meaning of his work. "Silence is so accurate," he said, fearing that words would only paralyze the viewer's mind and imagination.

The blue color occurs mostly in very old ice from a very deep glacier and is the result hundreds or even thousands of years of compression and ongoing thawing and refreezing of the ice. Over time, these processes release much of the air that was originally trapped by the falling snow. As this happens, the reflective surfaces of our "snowflakes" disappear. The ability to reflect light exists only when there is air between the surfaces of the ice crystals.
