In a space where Cartesian coordinates represent the excitations of the three cone types involved in color vision, a plane of constant luminance provides a chromaticity diagram in which excitation of each cone type (at constant luminance) is represented by a linear scale (horizontal or vertical), and in which the center-of-gravity rule applies with weights proportional to luminance.
在一个笛卡尔坐标表示参与颜色视觉的三种视锥细胞类型激发情况的空间中，一个恒定亮度平面提供了一个色度图，其中每种视锥细胞类型的激发（在恒定亮度下）由一个线性标度（水平或垂直）表示，并且在该色度图中重心规则适用，权重与亮度成比例。
