on numerous buildings in the historic area. The study, "the first modern scientific paint analysis" at Williamsburg, confirmed that the color palette did not represent historic color as first intended. In addition he found that some of the colors chosen were from later paint layers, some nineteenth-century. "Interestingly, many of the colors were still based on Susan Nash‘s early research. Four years ago, Benjamin Moore released the 'Williamsburg Color Collection.' Comprising 144 colors, this updated palette is the product of close collaboration with CWF experts using modern Architectural Paint Research methods including microscopy, instrumental analysis, and colorimetry complemented by archival research to provide a range, which is believed to accurately reflect 18th century Williamsburg‘s architectural finishes”. Based on this type of research, Colonial Williamsburg has undergone a paint restoration process to restore building colors and paint to their original intended appearance. Architectural anthropology Historic paint analysis can be utilized to further develop an understanding for how people may have lived or worked at a given time. One example of such an analysis can be seen in a study of the frescoes from Pompeii. An investigation at the temple of Venus at Pompeii characterized a new yellow/brown pigment specific to the region. The pigment analysis concluded that the color was composed of materials with a close chemical composition to the products of somma-vesuvius. This led researchers to suggest that there was a local production of this pigment in the region. Investigations such as this can allow researchers to understand how people may have lived or worked at a given point in history. Architectural dating Architectural dating from historic paint analysis can come from many different processes. The date, or period of a building can be sourced from the materials identified within the layers of pigment or finish, from a specific stylistic feature or technique, or historical records and evidence. Architectural dating can be used to identify a building's construction or structural changes. In some instances, changes in paint composition can be used for dating purposes, such as occurs in the instance of lead-based paints . Until 1977, lead was commonly used in paints to stabilize the pigment. In an investigation from the Osborn House, Isle of Wight, researchers were able to identify different levels of lead in three different layers of paint. This can help to identify the dates of major structural changes. If one room has lead paint where another
