1. 下载 .itermcolors 文件。
2. 打开 iTerm2 → 设置 → Profiles → Colors。
3. 打开 Color Presets → Import，选择文件，然后选中该预设。

一行安装命令：
curl -fsSL "https://terminalthemes.iwwi.app/ports/iterm2/github-light-high-contrast.itermcolors" -o "$HOME/Downloads/github-light-high-contrast.itermcolors"
# Import it in iTerm2 -> Settings -> Profiles -> Colors -> Presets.
