如何在VS Code的macOS zsh集成终端中修改代码输出颜色？

我想修改VS Code（macOS）里zsh集成终端的代码输出颜色，方便区分脚本输出和终端原有信息。修改主题、文本/背景/光标颜色都很简单，但单独改代码输出颜色却遇到了麻烦。

首先我在settings.json里尝试了以下配置：

"terminal.integrated.shellArgs.windows": [
     "-dumb", 
     "-c", 
     "echo -e '\\e[31m'"
]

但VS Code提示：

This is now deprecated. recommendation tells: 'the new recommended way to configure your default shell is by creating a terminal profile in terminal.integrated.profiles.windows and setting its profile name as the default in terminal.integrated.defaultProfile.windows. This will currently take priority over the new profiles settings but that will change in the future.`

接下来我改用终端配置文件的方式，尝试了如下配置：

"zsh": {
     "path": "zsh",
     "args": [
         "-l",
         "echo '\u001b[31m'"
     ]
}

但终端启动失败，报错：

The terminal process "/bin/zsh '-l', 'echo '[31m''" failed to launch (exit code: 127).

我知道可以在代码里通过ANSI转义序列实现颜色输出，比如Python里这么写：

print("\033[34mHello, world!\033[0m")

但我想知道，能不能直接通过VS Code的设置来实现单独修改代码输出颜色？
