建筑涂料的色彩选择与搭配

建筑涂料不仅对建筑物起着耐候、耐酸、耐碱、耐污染等保护功能，而且有着重要的美化装饰作用。一幢楼或一间房选用什么样颜色的涂料进行装饰，对居住者的生活情绪等也起着不可忽视的作用。这种作用是不明显的，往往不易被察觉。综观目前的建筑市场，装饰色彩对环境的影响，对人们的心理和情绪的作用，常常被忽视，而一味地追求光亮、艳丽，使得许多高层次、高档次的建筑失去了应有的光彩。人类通过生活的实践体验以及对大自然的长期观察，对不同的色彩形成了不同的印象和联想，换句话说，不同的色彩能给人们以不同的感觉。朱红、大红、深红…

基于WCS色彩管理系统跨媒体颜色复制准确性的研究

微软公司推出的Windows Vista操作系统采用WCS(Windows ColorSystem)色彩管理系统,利用基于测量的设备特性文件,结合相应的设备模型,得到设备颜色空间和标准颜色空间之间的映射.WCS采用CIECAM02色貌模型,所有的颜色转换都在CIECAM02中进行,从而可以预测不同视觉条件下的颜色视觉属性.本论文首先在分析研究由微软和佳能公司联合开发的新一代基于色貌模型CIECAM02的WCS色彩管理的特点和工作流程基础上,根据WCS设备模型特性文件方案和显示器测量数据,利用XML语言编写了显示器的WCS设备模型特性文件,设计出利用显示器模拟跨媒体色彩传输的实验路径和方法,使得跨媒体传输色彩的结果可以直观地进行评价;对ICC色彩管理系统下输出的图像和在WCS色彩管理系统下输出的图像进行了比较.结果进一步证实,WCS色彩管理系统较ICC色彩管理系统具有在色彩实时转换和跨媒体方面的优点.本课题的研究成果对利用WCS色彩管理系统实现高保真的色彩复制具有一定的指导意义.     

Investigation for the color samples with equi-depth in Natural Color System

The color depth, an important attribute of color, can reflect the amount of dye partly, which has important functions on the evaluation of color-fastness and strength of dyes, dyeing effect of fabric, computer color matching, and so on. Natural Color System, an internationally accepted color system, orders colors by three parameters (blackness, chromaticness, and hue). The color depth has not been specified within the Natural Color System. This article tries to find the regularity of the sample with equal-depth in Natural Color System. Firstly, 1950 color samples in Natural Color System were measured using an X-Rite Color i7 Spectrophotometer, and their color depths were calculated by five color depth formulas. Then, trend analysis and mathematical modeling methods were used to achieve the connection between the color depth and the notations of Natural Color System basing on color depth theories. Results show that, in Natural Color System, the color samples with the same distance to pure white do not have equal depth; but the color samples with the same nuance (equal blackness, whiteness and chromaticness) have broadly equal color depth, and their average coefficient values are lower than that of Society of Dyers and Colourists Standard Depths. Besides, regressive formulas were built, with which the color depths of any chips in Natural Color System can be calculated broadly by their notation.     

Color measurements for pearlescent coatings

This article describes recent developments at the National Institution of Standards and Technology in the colorimetric characterization of pearlescent coatings. The goal of this research is to develop a measurement protocol for the accurate color characterization of these coatings using an understanding of their scattering mechanism as a guide. A large ensemble of bi‐directional reflectance measurements on a series of pearl interference pigmented coatings show general trends in the color variations with illumination and viewing angles. These measurements were used to define a set of geometries (illumination angles of 15°, 45°, and 65° and aspecular angles of 15°, 35°, 45°, 70°, and 85°) to characterize the angle dependent color travel observed in these coatings. © 2003 Wiley Periodicals, Inc.

Color characteristics of Beijing's regional woody vegetation based on Natural Color System

Seasonality is a typical characteristic of Beijing's regional vegetation, and plant color is one of the most prominent visual factors of vegetation dynamic. In this research, we explored the composition and dynamic characteristics of plant color in Beijing's urban vegetation, involving the analysis of overall characteristics and respective features of leaf, flower, and fruit colors. Color data was collected from 177 woody plant species in Beijing Botanical Garden, spanning their annual life cycle, and identified with the colorimetry of the Natural Color System (NCS). Correlation and regression analyses were applied to reveal the temporal dynamic features of overall plant color richness. Cluster analysis was applied to categorize tree species based on typical colors of various plant organs. Color richness and color dispersion were introduced as two factors to measure color diversity of various tree species, applied in species evaluation by sorting and principal component analysis (PCA). Color dispersion of three‐dimensional NCS data was measured with a modified SD based on the calculation of mean spatial distance in the NCS space. Main results are as follows. The first part is plant color composition. The composition of all plant colors contains 862 NCS color species, 20 blackness species ranging from 3 to 90, 20 chromaticness species ranging from 0 to 90, 35 hue species ranging from G10Y‐B90G, and N. The second part is temporal dynamic of overall color richness. Leaf color richness and total color richness are significantly positively correlated with pentad (5‐day) sequence; flower color richness is significantly negatively correlated with pentad sequence; and fruit color richness first increases and then decreases over time. The third part is cluster analysis of tree species. Based on typical growing‐leaf color, various tree species were clustered into 6 categories; based on typical senescent‐leaf color, various tree species were clustered into 6 categories; based on typical flower color, various tree species were clustered into 15 categories; based on typical fruit color, various tree species were clustered into 7 categories. The fourth part is color diversity evaluation of various tree species with PCA. According to the PCA of flower‐leaf color diversity, the species with higher leaf color diversity and higher flower color diversity include Cotinus coggygria, Lagerstroemia indica, and Amygdalus triloba; the species with higher flower color diversity and lower leaf color diversity include Campsis radicans and Tamarix chinensis; the species with higher leaf color diversity and lower flower color diversity include Acer ginnala and Crataegus pinnatifida; the species with lower color diversity both for flower and leaf colors include Fontanesia fortune and Gleditsia sinensis. According to the PCA of leaf color diversity, the species with higher leaf color diversity in both leaf growth period and leaf senescence period include Diospyros kaki, Lagerstroemia indica and Paeonia suffruticosa; the species with higher leaf color diversity in leaf growth period and lower leaf color diversity in leaf senescence period include Amygdalus persica ‘Atropurpurea’ and Prunus virginiana ‘Canada Red’; the species with higher leaf color diversity in leaf senescent period and lower color diversity in leaf growth period include Quercus palustris, Armeniaca sibirica, and Metasequoia glyptostroboides; the species with lower leaf color diversity for the whole leaf development period include Gleditsia sinensis and Swida walteri.

CIECAM02色貌模型的视觉均匀性分析与模型优化

在Windows Vista操作系统中,微软公司新发布了WCS色彩管理系统替代原有的ICC色彩管理系统.新色彩管理系统的核心技术之一是:利用CIECAM02色貌模型置换ICC色彩管理中的CIELAB颜色模型,从而可以将人眼观察色彩时的环境等因素作为转换参数纳入色彩信息传输与再现的计算,使得在不同媒体或设备之间的色彩信息传输,从保证色度(chromaticity)测量值的正确传输转换为保证视觉效果的正确传输与再现.但实验证明,CIECAM02仍然存在视觉均匀性不够理想的缺点,这将会影响媒体或设备之间色彩信息转换的正确计算.本文首先利用国际上通用的四种色差评估数据(BFD、Leeds、RIT-DuPont和Witt)对CIECAM02进行局部视觉均匀性修正,优选出经过Witt修正后的明度(lightness)和Leeds修正后的彩度(chroma),然后再利用孟塞尔新标数据进行CIECAM02色貌模型整体均匀性修正.最后,用孟塞尔新标数据对修正前后的CIECAM02色貌模型进行检验.结果表明,修正后的CIECAM02色貌模型视觉均匀性无论是局部还是整体都有较大的改善.该实验成果不仅可以在计算机操作系统以及软件的色...
