如果你想保持简单，而不使用任何外部模块/学习新的api /破解核心控制台功能:

const LCERROR = '\x1b[31m%s\x1b[0m'; //red
const LCWARN = '\x1b[33m%s\x1b[0m'; //yellow
const LCINFO = '\x1b[36m%s\x1b[0m'; //cyan
const LCSUCCESS = '\x1b[32m%s\x1b[0m'; //green

const logger = class {
  static error(message, ...optionalParams) { console.error(LCERROR, message, ...optionalParams) }
  static warn(message, ...optionalParams) { console.warn(LCWARN, message, ...optionalParams) }
  static info(message, ...optionalParams) { console.info(LCINFO, message, ...optionalParams) }
  static success(message, ...optionalParams) { console.info(LCSUCCESS, message, ...optionalParams) }
}

// then instead (as presented in the accepted answer)
// console.error(LCERROR, 'Error message in red.');
// you write:

logger.error('Error message in red.');

// or with multiple parameters (only the message will be red):

logger.error('Error message in red.', 1, false, null, {someKey: 'whatever'});

// or use backticks (template literal) instead multiple params:

logger.error(`This will be red as ${foo} and ${bar} too.`);

现在您可以像使用控制台一样使用记录器。没有新的API需要记住……通常你会把它放到一个模块(logger.js)中，并导出类，以便在你的应用程序中随处使用它，因为const logger = require('./logger');

下面你可以找到运行node.js应用程序时文本的颜色引用:

console.log('\x1b[36m%s\x1b[0m', 'I am cyan');  //cyan
console.log('\x1b[33m%s\x1b[0m', stringToMakeYellow);  //yellow

注意%s是字符串(第二个参数)被注入的位置。\x1b[0m重置终端颜色，因此在此之后它不再继续是所选的颜色。

编辑:

例如，\x1b[31m是一个转义序列，它将被您的终端拦截，并指示它切换到红色。事实上，\x1b是不可打印控制字符转义的代码。仅处理颜色和样式的转义序列也被称为ANSI转义代码，并且是标准化的，因此它们(应该)适用于任何平台。

维基百科对不同终端显示颜色的方式做了很好的比较 https://en.wikipedia.org/wiki/ANSI_escape_code#Colors

这是控制台中可用颜色(包括背景和前景)的列表，带有一些可用的操作(如重置，反转等)。

const colours = {
    reset: "\x1b[0m",
    bright: "\x1b[1m",
    dim: "\x1b[2m",
    underscore: "\x1b[4m",
    blink: "\x1b[5m",
    reverse: "\x1b[7m",
    hidden: "\x1b[8m",
    
    fg: {
        black: "\x1b[30m",
        red: "\x1b[31m",
        green: "\x1b[32m",
        yellow: "\x1b[33m",
        blue: "\x1b[34m",
        magenta: "\x1b[35m",
        cyan: "\x1b[36m",
        white: "\x1b[37m",
        gray: "\x1b[90m",
        crimson: "\x1b[38m" // Scarlet
    },
    bg: {
        black: "\x1b[40m",
        red: "\x1b[41m",
        green: "\x1b[42m",
        yellow: "\x1b[43m",
        blue: "\x1b[44m",
        magenta: "\x1b[45m",
        cyan: "\x1b[46m",
        white: "\x1b[47m",
        gray: "\x1b[100m",
        crimson: "\x1b[48m"
    }
};

下面是一个如何使用它的例子:

console.log(colours.bg.blue, colours.fg.white, "I am a white message with a blue background", colours.reset) ; 
// Make sure that you don't forget "colours.reset" at the so that you can reset the console back to it's original colours.

或者你可以安装一些实用模块:

npm install console-info console-warn console-error --save-dev

当你使用这些模块时，它们会在控制台显示如下内容:

这是Windows 10的一种方法(可能适用于7)，它改变了cmd, npm终端本身的配色方案(主题)，而不仅仅是特定应用程序的控制台输出。

我找到了一个Windows插件——颜色工具，它应该是在Windows保护伞下开发的。在链接中有描述。

我将colortool目录添加到系统环境路径变量中，现在每当我启动终端(NodeJs命令提示符，cmd)时，它都可用。

2017:

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)
    );
  };
});

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。

Bright = "\x1b[1m"
Dim = "\x1b[2m"
Underscore = "\x1b[4m"
Blink = "\x1b[5m"

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"

BgRed = "\x1b[41m"
BgGreen = "\x1b[42m"
