Gridded construction of the Ostwald color system and its application

为了将奥斯特瓦尔德颜色系统应用到工业设计中,通过对经典奥斯特瓦尔德颜色系统的架构分析,构建了数字化奥斯特瓦尔德色立体及其可视化色谱。首先以色料染色获取红、黄、绿、蓝四个主色,通过二元耦合混色构建基于四主色的连续奥斯特瓦尔德数字化色相环及其混色色谱;以色料染色获取的最高明度的灰和最低明度的灰为基色,基于经典奥斯特瓦尔德八等级明度值的灰度轴,分别构建基于明度值等比、等差、非线性递增三种不同模式下的数字化灰度轴;分别采用等比、等差、非线性递增模式下的灰度轴与色相环中的每个纯色色块以三元耦合混色模式进一步构建数字化奥斯特瓦尔德色立体,并给出了24个等色相面、8个等白度面、8个等黑度面及8个等纯度面共计680个混色色块的颜色值;最后通过编制算法程序,实现了数字化奥斯特瓦尔德色立体的可视化,验证了基于色料染色获取的红黄绿蓝黑白六基色构建奥斯特瓦尔德颜色系统的可行性。

In order to apply the Ostwald color system to industrial design,a digital Ostwald color solid and its visual chromatogram are constructed through an architectural analysis of the classical Ostwald color system.Firstly,the four primary colors of red,yellow,green and blue are obtained by dyeing with color pigments,and the continuous Ostwald digitised hue ring based on the four primary colors and its mixing chromatogram are constructed by binary coupled mixing.Taking the highest brightness grey and the lowest brightness grey obtained from the dyeing of the pigment as the base colors,based on the grey scale axis of classical Ostwald's eight grades of brightness values,the digitised grey scale axes are constructed based on the brightness values of three different modes of equipartition,equipartition,and non-linear increment,respectively.The digital Ostwald color solid is further constructed by using the grey scale axis in the isometric,isotropic and non-linear incremental modes and each pure color block in the hue ring in the ternary coupled mixing mode,respectively,and the color values of 24 isochromatic surfaces,8 isotropic whiteness surfaces,8 isotropic blackness surfaces and 8 isotropic purity surfaces in a total of 680 mixing color blocks are given.Finally,the visualisation of digital Ostwald color solid is achieved through the preparation of algorithmic programs and the feasibility of constructing the Ostwald color system based on the six primary colors of red,yellow,green,blue,black and white obtained by dyeing the pigment is verified.
