照明光源及纸张色彩对传统书法作品展陈喜好的影响

书法是中国传统文化独有的文字艺术表现形式。书法作品的展陈喜好，其实质为色彩组合喜好中的色彩图形喜好问题。本研究针对现阶段书法作品展陈方式在颜色科学层面缺乏合理依据的问题，以主客观实验为基础，就照明光源及纸张色彩对传统书法展陈喜好的影响进行了分析与讨论。研究首先通过相关色温2 500, 3 500, 4 500, 5 500和6 500 K共五种典型LED照明光源相对光谱功率分布以及白色、黄白、浅白、红色、橙色共五种典型书法纸张光谱反射率信息的测量，获取光源及纸张色彩原始信息，并分别将其转换至CIEXYZ以及CIECAM02颜色空间。随后，将光源及纸张色彩属性与基于40名观察者心理物理学实验的1 000组书法展陈喜好数据进行关联性分析，进而从相关性分析、多元回归分析以及正态分布分析等多个统计学角度对传统书法作品展陈喜好的影响因素进行讨论。实验结果显示，传统书法作品展陈照明喜好与普通场景色彩喜好相比具有显著的特殊性，其喜好程度与明度对比、色相对比等色彩属性相关性较低，而主要受光源因素的影响。本研究的开展，将为当前传统书法作品的展陈照明工作提供有效的理论与方法参考，对于当前博物馆及美术馆的光源设计工作具有一定的指导意义。

Influence of Light Source and Paper Color on the Exhibiting Preference of Traditional Calligraphy

The Chinese calligraphy is a unique art of traditional Chinese culture.The core of color preference for Chinese calligra-phy is figural preference,which is a special kind of color combination preference.Currently,the exhibition of calligraphy is al-ways lack of scientific basis in the aspect of color science.In this research,the influence of light sources and paper color on the preference of traditional calligraphy was analyzed based on subj ective and obj ective experiments.The relative spectral power dis-tribution of 5 typical light sources (correlated color temperature:2 500,3 500,4 500,5 500 and 6 500 K)and spectral reflec-tance of 5 typical Chinese rice papers (white,orange,light white,red,yellow-white)were firstly measured and then trans-formed into CIEXYZ and CIECAM02 color space,respectively.Subsequently,the correlation between those colors attributes and 1 000 series of psychophysical experiment data from 40 observers on calligraphy exhibiting preference was analyzed.At last, the influence factors of the correlation were discussed form a multiple statistical point of view,such as normal distribution,cor-relation analysis and multiple regression.The experimental results indicated that the exhibiting preference of Chinese calligraphy is obviously different with that of ordinary color preference cases,for it is mainly affected by the attributes of lighting sources in-stead of the contrast of hue and lightness.The authors believe that the finding of the research will provided effective support for the development of calligraphy exhibiting in near future for museums and gallaries.
