为说明敦煌莫高窟第 85窟颜料目前所处的状态 ,用色度计和CIE1 976年表色系统进行选点监测 ,并进行X衍射分析。分析、监测结果表明 ,第 85窟颜料有 7种颜色 ,其中绿色颜料是最稳定的一种。颜色的色度值不仅反映了颜料当前所处的状态 ,而且对了解古代画师调色、技法、配比等提供一定的线索。这些信息对保护修复有指导性意义
In order to illustrate the current state of the pigment in Cave 85 of the Mogao Grottoes in Dunhuang, chrominance meters and CIE1 976 colorimetric system were used for spot monitoring and X-ray diffraction analysis. Analysis, monitoring results show that there are seven colors of paint at Cave 85, of which the green pigment is the most stable one. The chroma value of the color not only reflects the current state of the pigment, but also provides some clues for understanding the color, technique and matching of ancient painters. This information is instructive for the protection and restoration
