在HTML里，颜色有两种表示方式。一种是用颜色名称表示，比如blue表示蓝色。另外一种是用16进制的数值表示RGB的颜色值。RGB是Red，Green，Blue意思，RGB每个原色的最小值是0，最大值是255，如果换算成16进制表示，就是(#00)，(#FF)。比如白色的RGB(255,255,255)，就用#FFFFFF表示；还有黑色的RGB(0,0,0)，就用#000000表示。 注：在W3C制定的HTML 4 .0标准中，只有16种颜色可以用颜色名称表示(aqua, black, blue, fuchsia, gray, green, lime, maroon , navy, olive, purple, red, silver, teal, white, and yellow)，其它的颜色都要用16进制RGB颜色值表示。

种不同的系统保留颜色。以下就是216种Web安全颜色：#这个符号。56种Web安全颜色呢？因为Microsoft和Mac操作系统有。

当然 ，现在的浏览器支持更多的颜色名称。不过为保险起见，建议你还是采用16进制RGB颜色值来表示颜色。并且在值前加上#这个符号。

为了方便大家找到合适的颜色 ，我们在这里列了一些颜色说明 ，以供大家参考 ，不妨作为一种速查工具 。

Web安全颜色以前，很多电脑显示器最多支持256色，因此出现了216种Web安全颜色 ，以保证网页的颜色能够正确显示。

以下就是216种Web安全颜色：000000表示。以保证网页的颜色能够正确显示。

那为什么不是256种Web安全颜色呢？因为Microsoft和Mac操作系统有40种不同的系统保留颜色。

green, lime, maroon, navy, olive!
