CSS3色彩模式有哪些？CSS3 HSL色彩模式的定义

Posted in HTML / CSS onApril 26, 2016

HSL色彩模式是工业界的一种颜色标准，它通过对色调（H），饱和度（S），亮度（L）三个颜色通道的改变以及他们相互之间的叠加来获得各种颜色。这个标准几乎包括了人类视力可以感知的所有颜色，在屏幕上可以重现16777216种颜色，是目前应用最广的颜色系统之一。

语法：

hsl（<length>,<percentage>,<percentage>）

参数说明：

<length>表示色调（Hue），Hue衍生于色盘，取值可以为任意数值，其中0（或360或-360）表示红色，60表示黄色，120表示绿色，180表示青色，240表示蓝色，300表示洋红，当然可以设置其他数值来确定不同的颜色。

<percentage> 表示饱和度（Saturation），表示该色彩被使用了多少，即颜色的深浅程度和鲜艳程度。取值为0%到100%之间的值，其中0%表示灰度，即没有使用该颜色；100%的饱和度最高，即颜色最鲜艳。

<percentage> 表示亮度（Lightness），取值为0%到100%之间的值，其中0%表示最暗，显示为黑色；50%表示均值，100%最亮，显示为亮色。
