The 1,700 square foot “History of Ipswich,” mural, painted on the wall of an old mill building, traces local history from the 1600s to the present day. This portion of the mural was painted on three walls that were perpendicular to each other. The most brilliant colors are the result of full sunlight, while all else falls into shadow. We see here how sunlight creates contrast and saturation, compared to the flattening effect of shadow on color.
