色度 (色彩学) Colorfulness

Photoshop中调节色度的效果

色度指得是色彩的纯度,也叫饱和度彩度,是“色彩三属性”之一。如大红就比玫红更红,这就是说大红的色度要高。它是HSV色彩属性模式,孟塞尔颜色系统等的描述色彩变量。

从广义上说,黑白灰是“色度=0”的颜色。在各种色彩模型中,对色度有不同的量化模式。

色度由光线强弱和在不同波长的强度分布有关。最高的色度一般由单波长的强光(例如激光)达到,在波长分布不变的情况下,光强度越弱则色度越低。

在三原色光模式中,色度可定量化用σ表示某一色彩与纯色的差别:

 \sigma = \sqrt{(R - \mu)^2 +(G - \mu)^2 +(B - \mu)^2 \over 3}

上述是一个简化的例子。定色法中有更复杂的定义。
