Robin Coste Lewis Using Black to Paint Light: Walking Through a Matisse Exhibit Thinking about the Arctic and Matthew Henson: In this text, Coste Lewis writes "so much believed to be white is actually—strikingly—blue." She describes the lack of visibility of blue, then, as it is often mistaken for white. She further comments on visibility when describing her accident: "Because it was dark, I could see, really see—for the first time—how a particular gold thread sparkled on the collar. I reached out my hand. But before the wall, there was a large hole where stairs were being built, which I could not see." In these lines, she juxtaposes the visibility of the thread, even in the dark, with the invisibility of the hole that she fell through.
