网页设计制作之改进超级链接效果-XHTML教程

Conclusion
结论

On balance, it seems that the predominant convention in the industry is to keep #00f or #00c (slightly darker) blue for links, and to make links red and (optionally) underlined on hover.

总而言之，最具特点的超链接颜色效果变化是：使用 #00f 或 #00c（颜色较前者稍微暗点），作为超链接的字体颜色；当鼠标经过时，使用红色或者加上一条下滑线来突显它。

I think that this provides the best balance of functionality when applied consistently to inline hyperlinks and grouped hyperlinks.

我认为：对所有的内置超链接和群组超链接使用相同的效果变化能够在其功能性保持最好的平衡。
