您可以使用这种CSS快速方便地为标签设置自己的颜色集：

.label-default {
  background-color: #999;
}
.label-default[href]:hover,.label-default[href]:focus {
  background-color: #808080;
}
.label-primary {
  background-color: #428bca;
}
.label-primary[href]:hover,.label-primary[href]:focus {
  background-color: #3071a9;
}
.label-success {
  background-color: #5cb85c;
}
.label-success[href]:hover,.label-success[href]:focus {
  background-color: #449d44;
}
.label-info {
  background-color: #5bc0de;
}
.label-info[href]:hover,.label-info[href]:focus {
  background-color: #31b0d5;
}
.label-warning {
  background-color: #f0ad4e;
}
.label-warning[href]:hover,.label-warning[href]:focus {
  background-color: #ec971f;
}
.label-danger {
  background-color: #d9534f;
}
.label-danger[href]:hover,.label-danger[href]:focus {
  background-color: #c9302c;
}

这里有2套：

>默认值：#95a5a6 /#7f8c8d
> primary：#3498db /#2980b9
>成功：#2ecc71 /#27ae60
> info：#9b59b6 /#8e44ad
