The intangible cultural heritage of Yangjiabu New Year woodblock paintings (YNYWPs) has numerous potential cultural, artistic, and economic values. The quantitative color characteristics of YNYWPs, which have always been disregarded, can offer evidence in support of their inheritance and conservation. Utilizing the principles and methods of color science and spectral imaging technology, the color characteristics, including spectral characteristics, colorimetric characteristics, and color combination regularity, were quantitatively investigated by measuring and capturing the representative works. The results show that the spectral reflectances of the seven colors (i.e., red, yellow, green, cyan, violet, black, and paper color) adopted in the selected paintings have no significant structured features and can be accurately described using the first six derived eigenvectors by principal component analysis. The Xuan paper and the yellow color have higher reflectance than the other five colors. Correspondingly, their Commission Internationale de l'Eclairage (CIE) 1964 XYZ stimulus values are also relatively high. The others cover a narrow range in the CIE XYZ system. When transformed into the CIELAB color space, the seven colors can be relatively uniformly distributed in the color space. With regards to the color combination regularity, red, yellow, and cyan tend to occupy a large area in the selected paintings. In contrast, the other colors, especially green, are not frequently used. The resulting data of the color combination regularity quantitatively verify the color combination knack that is transmitted by word of mouth from generation to generation.

基于色彩科学与光谱成像的杨家埠木版年画色彩特征定量分析

杨家埠木版年画作为非物质文化遗产，具有众多潜在的文化、艺术和经济价值。一直被忽视的YNYWP的定量颜色特征可以为其遗传和保护提供证据。运用色彩科学和光谱成像技术的原理和方法，通过测量和捕捉代表性作品，定量研究色彩特性，包括光谱特性、色度特性和色彩组合规律。结果表明，所选画作中采用的七种颜色（即红、黄、绿、青、紫、黑和纸色）的光谱反射率没有显着的结构特征，可以使用前六种推导出来准确描述通过主成分分析得到特征向量。宣纸和黄色的反射率高于其他五种颜色。相应地，他们的国际照明委员会（CIE）1964 XYZ刺激值也相对较高。其他覆盖 CIE XYZ 系统中的狭窄范围。当转换到CIELAB色彩空间中时，七种颜色可以在色彩空间中相对均匀地分布。从色彩组合规律来看，所选画作中红、黄、青色往往占据较大面积。相比之下，其他颜色，尤其是绿色，并不经常使用。所得到的色彩组合规律数据定量地验证了代代相传的色彩组合诀窍。
