three-dimensional representation of a color space or model; can be thought as an analog of the one-dimensional color wheel, which depicts the variable of hue; or the 2D chromaticity diagram, which depicts the variables of hue and spectral purity

色立体是一种三维表示的色彩空间，类似于二维表示的色环。色立体额外增加的维度使得它可以额外多表现一个维度的色彩变化。二维色轮通常表现色相的变化（红，绿，蓝等）和明度（明暗层次），而色立体多了一个饱和度，这使得色立体可以在三维结构中表现出所有可能的颜色。
