In order to conserve color on various cultural properties, examination and recording of deterioration of color are performed and developed as well as fixing and re-adhering treatment for the color.(1)X-ray deffraction method was employed for identifying the pigments which were used by a painter for national important wooden building, and found that two different pigments are used with one name depending on the works.(2)Raking light apparatus was developed and a first model for practical use was made up. The apparatus projects parallel light beam with fixed angle and even light value at any point of a flat object, and gives ideal lighting condition for taking photo of recording damaged color layer.(3) Red lead color on wood was examined after artificial aging by weathering chamber, to know the minimum concentration of animal glue in which the red lead color started peeling after the aging. It was confirmed that color layer which was prepared with acrylic resin as a medium, showed good durability in its high concentration.(4)Degree of discoloration was measured on three pigments on wood which were traditionally used by painters for wooden building.(5)The ratio of hydroxy-proline to other amino-acid contained in three kinds of animal glue, was found to indicate the source of the glue.(6)The condition of color on wooden member of shrines and temples were surveyed. Paintings on paper of sliding door and a wooden ornament were examined for remained color layers.

为了保护各种文化财产的颜色，进行和开发颜色劣化的检查和记录以及颜色的固定和重新粘附处理。（1）用X射线衍射法对某国家重点木构建筑画家所用颜料进行鉴定，发现不同作品所用颜料有两种不同的名称。（2）研制了耙光装置，并制作了第一个实用模型。该装置在平面物体的任意点投射出具有固定角度和均匀光值的平行光束，为记录受损色层的照相提供了理想的照明条件。(3)采用人工老化试验箱对人工老化后木材表面的红丹色进行检测，以确定人工老化后红丹色开始剥落的最低动物胶浓度。证实了以丙烯酸树脂为介质制备的着色层在其高浓度下显示出良好的耐久性。（4）测量了木材上传统上由油漆工用于木建筑的三种颜料的变色程度。（5）三种动物胶中羟脯氨酸与其它氨基酸的比值可作为判断胶源的依据。（6）调查了寺庙、佛龛木构件的色彩状况。对拉门和木饰的纸上绘画进行了残留色层的检测。
