Sublime Text 2 中突出显示的颜色表示什么？

Question

我在文件中有这段代码：

background: -moz-linear-gradient(red, orange, yellow, green, blue, indigo, violet);

Sublime Text 2 似乎用浅蓝色突出了 indigo 和 violet 的背景：

我尝试了更多的颜色，其中大多数颜色如 chocolate、aliceblue、pink 等被突出显示，但其他一些颜色如 maroon、teal, silver 等没有。

蓝色突出显示是什么意思？

这些是"Extended color keywords"

X11 colors [X11COLORS] supported by popular browsers with the addition of gray/grey variants from SVG 1.0. The resulting list is precisely the same as the SVG 1.0 color keyword names. This specification extends their definition beyond SVG.

不同的外观是由作用域造成的：

support.constant.color.w3c-standard-color-name.css（对于标准颜色关键字）
invalid.deprecated.color.w3c-non-standard-color-name.css（用于扩展颜色关键字）
