vim-colorschemes 是一个很好的主题合集，vim 的主题都放在 ~/.vim/colors 下（neovim 的放在 init.vim ?），没有请 mkdir ~/.vim/colors然后终端运行：

git clone https://github.com/flazz/vim-colorschemes.git ~/vim-colorschemes
cp ~/vim-colorschemes/colors/* .vim/colors

• 在 vim 界面使用 :colorscheme <按tab> 和 Enter 来预览主题，永久使用主题需要写入 vimrc 配置文件（见最后面）

• 调整默认主题的技巧：针对 LightDefault 主题

  • 可以开两个终端界面，一个更改主题配置（使用 :w 而不是 :wq 来保存不退出），一个使用 :colorscheme LightDefault 命令来更新主题

  • 例如弹出框的背景色默认为 Magenta （紫红色）修改成 White、选中项改成和滚动条 LightCyan （淡青色）；行号默认为 Yellow （黄色）要修改成 LightGrey（浅灰色），可以在 ~/.vim/colors/LightDefault.vim / 配置文件 添加以下内容：

    hi LineNr ctermfg=LightGrey
    hi Pmenu ctermbg=White
    hi PmenuSel ctermbg=LightCyan
    hi PmenuSbar ctermbg=White
    hi PmenuThumb ctermbg=Yellow

    提醒：修改配置不会对正在编辑文件的 vim 生效，如果要生效：在编辑文件窗口 :source 修改的配置文件 。或者 使用命令 hi Pmenu ctermbg=White 之类的临时预览，确定之后修改配置再重新打开所编辑的文件。

  • 使用 [:h highlight-ctermfg](http://vimhelp.appspot.com/syntax.txt.html#highlight-ctermfg) 查看支持的颜色名称（不支持 hex 颜色）：

    ctermbg={color-nr}              *highlight-ctermbg*
    The {color-nr} argument is a color number.  Its range is zero to
    (not including) the number of tui-colors available.
    The actual color with this number depends on the type of terminal
    and its settings.
    [...]
    The following (case-insensitive) names are recognized:
                       *cterm-colors*
    NR-16   NR-8    COLOR NAME ~
    0       0       Black
    1       4       DarkBlue
    2       2       DarkGreen
    3       6       DarkCyan
    4       1       DarkRed
    5       5       DarkMagenta
    6       3       Brown, DarkYellow
    7       7       LightGray, LightGrey, Gray, Grey
    8       0*      DarkGray, DarkGrey
    9       4*      Blue, LightBlue

    The ‘statusline’ syntax allows the use of 9 different highlights in the statusline and ruler (via ‘rulerformat’). The names are User1 to User9.

For the GUI you can use the following groups to set the colors for the menu, scrollbars and tooltips. They don’t have defaults. This doesn’t work for the Win32 GUI. Only three highlight arguments have any effect here: font, guibg, and guifg.

# 设置 gui 颜色
参考：[https://vi.stackexchange.com/questions/13458/make-vim-show-all-the-colors](https://vi.stackexchange.com/questions/13458/make-vim-show-all-the-colors)
1. 在 vim 的配置文件中开启 gui：
```bash
set termguicolors

1. 终端（或者模拟终端）软件必须支持和开启真彩色(true color)
2. 配置 highlight ：使用 guifg guibg gui 等参数。

把 hi 的配置项链接到另一个配置项

参考：https://stackoverflow.com/questions/26958070/how-do-i-link-highlighting-groups-in-a-vim-colour-scheme
例子：把 ErrorMsg 的配置链接到 Error

highlight Error            ctermbg=161
highlight ErrorMsg         NONE
highlight link ErrorMsg    Error

Error 必须已经被设置； ErrorMsg 必须被清除配置：如果不使用 NONE 来清除，则可以用 highlight! link ErrorMsg Error 来替代后两行语句。
