民族织锦的主色提取方法

传统民族织锦色彩丰富,其独特的色彩搭配是设计师重要的设计灵感来源。为找到适合民族织锦的主色提取方法,使用不同方法提取民族织锦主色并进行分析。首先采用优化K-means算法、基于HLS色彩空间的色彩分层及使用Photoshop软件对民族织锦进行主色提取,构建8色或10色的主色卡,用提取的主色重构织锦图片;其次,对民族织锦主色卡从CIELAB、RGB色彩空间的角度对比分析;最后建立壮、黎、土家族织锦相应的主色卡。研究结果表明:Photoshop软件更适合用于民族织锦的主色提取;壮、黎、土家族在色彩的搭配使用上存在着一定的地域共性,均与我国传统的“五行正色”有关;Photoshop软件主色提取法可为设计师在色彩提取过程中提供参考与借鉴。

Primary color extraction method for brocade

Traditional ethnic brocades are rich in colors, and their unique color collocation is an outstanding source for design inspiration to designers. Aiming to find a suitable method to extract the primary colors of ethnic brocade, different methods were used to extract and analyze them. We used the K-means optimization algorithm, color layering method based on HLS color space, and Photoshop software to extract the primary colors of ethnic brocade. 8-color or 10-color primary color cards were constructed, based on which the brocade pictures with the extracted primary colors were reconstructed. Following that, a comparative analysis of the primary color card sof ethnic brocades from the perspective of Lab value and RGB value shows that Photoshop software is more suitable for the primary color extraction for ethnic brocades. Finally, the corresponding primary color cards of Zhuang, Li, and Tujia brocade were established. Zhuang, Li, and Tujia ethnic groups have certain regional commonness in the use of color collocation, which is related to the traditional "five elements of positive colors". Through analysis, it is concluded that the use of Photoshop to extract the primary colors of ethnic brocades can provide a reference for designers in the process of color extraction.
