This note describes a way of extending the physical lights inside the spectrum locus to supersaturated colors related to them by a Von Kries transformation. The extension is one-way but quantitative: One can see a supersaturated light in a given state of chromatic adaptation, and one can compute its chromaticity through a proportion based on three physical lights, but one cannot further connect the perception and the computed chromaticity to test the adaptation model that is used to make the construction. The construction may nonetheless be useful in delimiting the chromaticities that are computed as intermediate states in a color-management system.

Von-Kries 增强色域

本笔记描述了一种通过 Von Kries 变换将光谱轨迹内的物理光扩展到与它们相关的过饱和颜色的方法。扩展是单向但定量的：在给定的色适应状态下可以看到过饱和光，并且可以通过基于三个物理光的比例计算其色度，但不能进一步将感知和计算出的色度连接到测试用于构建的适应模型。尽管如此，该构造在界定作为颜色管理系统中的中间状态计算的色度时可能是有用的。
