Diagram 的 sequence/flow 颜色过淡

[Deleted user]

```sequence
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!
```

```flow
st=>start: Start
op=>operation: Your Operation
cond=>condition: Yes or No?
e=>end

st->op->cond
cond(yes)->e
cond(no)->op
```

发现和 css 里 .md-fences, tt 的 color 有关

.md-fences, tt {
  border-radius: 3px;
  color: #f0f0f0;
  padding: 0;
  font-size: 0.9em;
}

如图所示

.md-fences, tt {
  color: #183055;
}

.md-fences .code-tooltip {
  background-color:#F0F0F0;
}

尴尬，我不经常用这个，都没发现，我下个版本会修复

[HanryYu]

的确是 .md-fences, tt 的问题，新版已经release

[Deleted user]

修改完 .md-fences, tt 可能还需要修改 .md-fences .code-tooltip 的 background-color

我是个外行，不知道他们的具体含义

tt 似乎是标识代码块语言的
.code-tooltip 的 color 是代码块语言的背景色

最新的commit修复了，昨天没注意这个问题，我没有release，你可以直接在仓库更新blubook.css
