Two questions are mainly discussed in this article: (a) how the shape of color order systems is related to different types of chromatic mixtures, and (b) how the opacity or transparency (an aspect of cesia) of the coloring media involved in the mixtures define the results, beyond the established categories of additive, partitive, and subtractive mixtures. The degree of transparency, translucency, or opacity of the material used certainly has a great influence on these processes and in the results obtained, and we could also think that the degree of gloss or matte finish of the surfaces affects the mixtures as well. The underlying idea is that these processes are of a gradualist nature, and that a continuous sequence can be traced between two poles: additive mixture of overlapping lights, on one side, and subtractive mixture of transparent color layers, on the other one. Thus, instead of just three separate or unconnected types of color mixtures, we can postulate a model based upon a gradual sequence between additive and subtractive mixture, with partitive mixture as one of the steps in between. A schematic 3D model of gradual transformation is proposed to encompass different color systems that represent any possible mixture between additive and subtractive.

色序系统、颜色混合和 cesia 的作用

本文主要讨论两个问题：(a) 色序系统的形状如何与不同类型的色彩混合相关，以及 (b) 着色介质的不透明度或透明度（cesia 的一个方面）如何参与混合物定义了结果，超出了加法、部分和减法混合物的既定类别。所用材料的透明度、半透明性或不透明度肯定对这些过程和获得的结果有很大影响，我们也可以认为表面的光泽度或哑光度也会影响混合物。潜在的想法是，这些过程具有渐进性，并且可以在两个极点之间追踪一个连续的序列：重叠光的加法混合，在一侧，和透明色层的减法混合，在另一个上。因此，我们可以基于加法混合和减法混合之间的逐渐序列假设一个模型，而不是仅仅三种单独或不相关的颜色混合类型，其中部分混合是介于两者之间的步骤之一。提出了一个渐进变换的示意性 3D 模型，以包含代表加法和减法之间任何可能混合的不同颜色系统。
