觉得 Adams 主题自带的夜间模式（深夜蓝）色值：#1c1f2b 还不够黑，所以重新调整了配色方案。
你可以在外观> 自定义> 额外 CSS 把 CSS 内容拷贝进去，点发布就可以。我测试的时候就是这么操作的。
“额外 CSS” 虽然可以用，但总觉得页面打开的速度有点慢，而且这个深夜蓝的夜间模式我也不打算继续用，所以干脆覆盖 CSS 内容了。
- 打开 Adams 主题内的
style.css - 找到
/* 夜间模式 */ - 复制替换掉原有的 CSS 内容
- 保存上传便可。
如果你使用了缓存，可以随意更新一篇文章，刷新一下缓存就 OK。
Tips: 切记备份原 css 文件！！免得到时候没有后悔药吃。
以下就是 CSS 代码：

补充一下修改 CSS 文件遗漏的地方：图片灯箱背景颜色
位置：第 720 行
body.night .view-img {
background: rgba(28, 31, 43, 0.9) !important;
}将 rgba 里面的颜色值修改为 rgba(18, 18, 18, 0.9)便可。
