基于色彩方案重用的产品配色感性设计

Product color design based on reuse of color scheme

在工业设计界,产品配色活动主要依靠人工赋色和修改,并且用户感性知识参与性较低.为了有效降低设计活动对领域知识的依赖以及增强用户感性需求的满意度,提出了基于色彩配置方案重用的产品配色感性设计方法.运用模糊处理与主色提取等技术从源图像中获取色彩组合方案,建立色彩组合样本库、产品三维模型库及色彩组合感性评价语义集,利用因子分析方法从色彩组合方案中提取单个色彩的意象贡献值,进而完成从独立色彩空间向意象词汇空间的映射,依据用户评价分值与色彩调和度构建适应度评价函数并以交互式遗传算法为工具推进方案群的优化.以文化旅游纪念品配色设计为例对设计方法进行验证,表明该方法的有效性.

In the field of industrial design,product coloring activity is mainly colored and modified manually and the usersemotional involvement is low.In order to reduce the dependence on the knowledge in the design activities,a color design method based on reuse of color configuration was proposed.It used obfuscation and dominant color extraction technology to obtain color combinations from the source image,then created the sample database of color combinations,the 3D model library of products and the emotional evaluations collection of color combinations.The imagery contribution of single color was obtained from the color combination by using factor analysis.Then it completed the mapping from independent color space to the imagery space.Finally,based on users evaluation scores and color harmony,fitness function was built and the optimization of program groups was promoted through IGA.An example of cultural souvenir color design demonstrates the effectiveness of this method.
