CSS系统默认颜色

直接调用系统的颜色显示在网页上本来是件很好玩滴事，但是，也有个缺点，就是可用的色太少 比如Bindows在它的启动画面一点点应用。

=。= 上次本来想在某个产品上应用，结果给人BS了，原因是色不好看 囧rz

在css21 中 System Colors也有相关描述，CSS3还加了超链接的色，还有个flavor。

但是，要有浏览器支持才是硬道理，浏览器不支持，虾米都回家睡觉。

附各色显示效果，如果看不到文字部分就像刮彩票一半刮开看一下，其中，Background 这个在safari 比较神奇，是透明哦。

• flavor

• An accent color (typically chosen by the user) to customize the user interface of the user agent itself. User agents may default the ‘flavor’ color to the dominant accent color used on the physical machine/mechanism that the user is interacting with (frequently a mouse, keyboard, monitor and computer case, often just a laptop), if the UA is able to retrieve that information from the platform and machine. It is not expected that this value will make sense on all platforms and machines.
