Inspired by the pioneer work of H.L. Resnikoff, which is described in full detail in the first part of this two-part paper, we give a quantum description of the space $\mathcal{P}$ of perceived colors. We show that $\mathcal{P}$ is the effect space of a rebit, a real quantum qubit, whose state space is isometric to Klein’s hyperbolic disk. This chromatic state space of perceived colors can be represented as a Bloch disk of real dimension 2 that coincides with Hering’s disk given by the color opponency mechanism. Attributes of perceived colors, hue and saturation, are defined in terms of Von Neumann entropy.

颜色感知的几何形状。第2部分：从真实的量子态和Hering的重击感知的颜色。

受到HL Resnikoff的先驱作品的启发（本两部分的第一部分对此进行了详细介绍），我们对感知颜色的空间$ \ mathcal {P} $进行了量子描述。我们证明$ \ mathcal {P} $是一个位的作用空间，即真实的量子量子位，其状态空间与Klein双曲圆盘等距。可以将感知到的颜色的这种色状态空间表示为实数为2的Bloch圆盘，该圆盘与颜色对调机制所给定的Hering圆盘重合。根据冯·诺依曼熵来定义感知的颜色，色相和饱和度的属性。
