我不想要任何依赖于此，只有这些在OS x上为我工作。所有其他示例从这里的答案给了我八进制文字错误。

Reset = "\x1b[0m"
Bright = "\x1b[1m"
Dim = "\x1b[2m"
Underscore = "\x1b[4m"
Blink = "\x1b[5m"
Reverse = "\x1b[7m"
Hidden = "\x1b[8m"

FgBlack = "\x1b[30m"
FgRed = "\x1b[31m"
FgGreen = "\x1b[32m"
FgYellow = "\x1b[33m"
FgBlue = "\x1b[34m"
FgMagenta = "\x1b[35m"
FgCyan = "\x1b[36m"
FgWhite = "\x1b[37m"
FgGray = "\x1b[90m"

BgBlack = "\x1b[40m"
BgRed = "\x1b[41m"
BgGreen = "\x1b[42m"
BgYellow = "\x1b[43m"
BgBlue = "\x1b[44m"
BgMagenta = "\x1b[45m"
BgCyan = "\x1b[46m"
BgWhite = "\x1b[47m"
BgGray = "\x1b[100m"

对于一个不影响String对象的内置方法的流行替代颜色，我推荐使用cli-color。

包括颜色和可链接样式，如粗体、斜体和下划线。

有关此类别中各个模块的比较，请参见这里。

另一种方法是使用一个简单的ANSI代码生成器。

您不需要安装软件包 不需要搜索颜色代码，只需点击按钮

你可以在https://console-colors.vercel.app/上使用它

最小的别名:

{
  const f = (color) => (...args) => {
    for (const x of [color, ...args, "\33[0m"]) console.log(x);
  };

  Object.assign(console, {
    black: f("\33[30m"),
    red: f("\33[31m"),
    green: f("\33[32m"),
    yellow: f("\33[33m"),
    blue: f("\33[34m"),
    magenta: f("\33[35m"),
    cyan: f("\33[36m"),
    white: f("\33[37m"),
  });
}

// Usage
console.blue("Blue world");

简单的方法，为消息添加时间颜色，你不需要改变你的代码，使用keep your console.log('msg')或console.err('error')

var clc = require("cli-color");
var mapping = {
  log: clc.blue,
  warn: clc.yellow,
  error: clc.red
};

["log", "warn", "error"].forEach(function(method) {
  var oldMethod = console[method].bind(console);
  console[method] = function() {
    oldMethod.apply(
      console,
      [mapping[method](new Date().toISOString())]
      .concat(arguments)
    );
  };
});

If you are using Windows CMD then go to the terminal Properties/Colors (CMD top left) and then redefine the RGB value of the offensive color. In my case I believe it's the fifth color square from the left, which I changed to (222,222,222). It does not matter if the currently selected radio button shows Screen Text or Screen Background as you just redefine that specific "system" color. Once you changed the color don't forget to select back the preferred color for the background or text before clicking OK.

更改后，所有来自Node(在我的情况下是Ember)的红色消息都清晰可见。
