感谢分享。有一个容易混淆的小问题:本文提到的RGB、HSV、HSL是色彩模型(color model),即一种表示颜色的“方式”,而不是色彩空间(color space)。 仅靠色彩模型是无法定义色彩的,如RGB中,即使给定了一组分别代表R、G、B的三元数组,由于R、G、B分别对应的原色未知,是无法计算出其代表的颜色的。只有加上了三原色...

HSL & HSV HSL and HSV are two related representations of points in an RGB color model that attempt to describe perceptual color relationships more accurately than RGB, while remaining computationally simple. HSL stands for hue, saturation and lightness, while HSV stands for hue, saturation and val...
HSL即色相、饱和度、亮度(英语:Hue, Saturation, Lightness)。HSV即色相、饱和度、明度(英语:Hue, Saturation, Value),又称HSB,其中B即英语:Brightness。 色相(H)是色彩的基本属性,就是平常所说的颜...RGB、HSL、HSV及各种颜色选择器界面 你知道吗?原来颜色是种四维产物。 色彩体系模型 我们知道,在描述一个...

The Lightness value of an HSL color is in a third dimension, which actually makes the HSL system a cylinder:What is HSV color model ?HSV (Hue, Saturation and Value) – defines a type of color space. It is similar to the modern RGB and CMYK models. The HSV color space has three ...
Joblove and Greenberg[11] described the HSL model—whose dimensions they labeled hue, relative chroma, and intensity—and compared it to HSV (fig. 1). Their model was based more upon how colors are organized and conceptualized in human vision in terms of other color-making attributes, such ...
