以下是翻译好的部分：
有一些使用伪类和选择器来改变颜色的方法。
<selector>:hover {
/*
当鼠标移动到链接上时，你可以在这里做一些变化。
*/
}
<selector>:focus {
/*
这意味着当鼠标按住鼠标左键并保持按下时，可以在这里进行一些变化。
*/
}
<selector>:visited {
/*
这可能是你希望在用户访问链接后执行的效果。
*/
}
还有更多的伪类可以使用，请查看以下链接。

英文:
There are few way to change color with pseudo-classes with selectors.
<selector>:hover {
/*
when the mouse move over to the link then you can do something change in here.
*/
}
<selector>:focus {
/*
which means that when the mouse hold the mouse left click keep press do something change in here.
*/
}
<selector>:visited {
/*
this might you want effect when user visited the link css to do.
*/
}
