Colors are displayed combining RED, GREEN, and BLUE light sources.
颜色是由红色，绿色和蓝色光所组合起来的
颜色值
CSS colors are defined using a hexadecimal notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one light source is 0 (hex #00). The highest value is 255 (hex #FF).
CSS颜色可以使用RGB记号法来表示，或是十六进制数来表示。
This table shows the result of combining Red, Green, and Blue light sources:.
这张表所显示的结果就是三原色混合后的结果：
| 颜色 | 十六进制色 | RGB色 |
|---|---|---|
| #000000 | rgb(0,0,0) | |
| #FF0000 | rgb(255,0,0) | |
| #00FF00 | rgb(0,255,0) | |
| #0000FF | rgb(0,0,255) | |
| #FFFF00 | rgb(255,255,0) | |
| #00FFFF | rgb(0,255,255) | |
| #FF00FF | rgb(255,0,255) | |
| #C0C0C0 | rgb(192,192,192) | |
| #FFFFFF | rgb(255,255,255) |
颜色名称
A collection of color names is supported by most browsers.
一组基本上所有浏览器都支持的颜色名称
Note: Only 16 color names are supported by the W3C CSS standard (aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow). For all other colors you should use the Color HEX value.
注意：只有16种颜色名称是符合W3S中CSS标准的,它们分别是(aqua, black, blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow)。所有其它的颜色应该使用十六进制色值
| 颜色 | 十六进制色 | 颜色名称 |
|---|---|---|
| #F0F8FF | AliceBlue | |
| #FAEBD7 | AntiqueWhite | |
| #7FFFD4 | Aquamarine | |
| #000000 | Black | |
| #0000FF | Blue | |
| #8A2BE2 | BlueViolet | |
| #A52A2A | Brown |
Web 安全色
A few years ago, when most computers supported only 256 different colors, a list of 216 Web Safe Colors was suggested as a Web standard. The reason for this was that the Microsoft and Mac operating system used 40 different "reserved" fixed system colors (about 20 each).
几年前，当大多数计算机只支持256种颜色的时候，有一列216色的网页安全色是被WEB所支持的。原因是微软公司和MAC的操作系统使用了40种不同的颜色混合系统。（大约每二十个就有一个）
We are not sure how important this is now, since more and more computers are equipped with the ability to display millions of different colors, but the choice is left to you.
我么不敢肯定这个有多么重要，尤其是现在的计算机越来越先进，可以显示上百万种不同的颜色，但这个最终的决定权还是取决于你自己。
216色交织平台
This 216 cross platform web safe color palette was originally created to ensure that all computers would display all colors correctly when running a 256 color palette.
这个平台最初只是为了来确定在256色的颜色模式下计算机是否能正常显示这些颜色。
