例如，如果你想有一个昏暗的红色文本和蓝色背景，你可以在Javascript中这样做:

console.log("\x1b[2m", "\x1b[31m", "\x1b[44m", "Sample Text", "\x1b[0m");

颜色和效果的顺序似乎不是那么重要，但总是记得在最后重置颜色和效果。

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');

我重载了控制台方法。

var colors={
Reset: "\x1b[0m",
Red: "\x1b[31m",
Green: "\x1b[32m",
Yellow: "\x1b[33m"
};

var infoLog = console.info;
var logLog = console.log;
var errorLog = console.error;
var warnLog = console.warn;

console.info= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Green);
    copyArgs.push(colors.Reset);
    infoLog.apply(null,copyArgs);
};

console.warn= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Yellow);
    copyArgs.push(colors.Reset);
    warnLog.apply(null,copyArgs);
};
console.error= function(args)
{
    var copyArgs = Array.prototype.slice.call(arguments);
    copyArgs.unshift(colors.Red);
    copyArgs.push(colors.Reset);
    errorLog.apply(null,copyArgs);
};

// examples
console.info("Numeros",1,2,3);
console.warn("pares",2,4,6);
console.error("reiniciandooo");

输出为。

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

var colorSet = {
    Reset: "\x1b[0m",
    Red: "\x1b[31m",
    Green: "\x1b[32m",
    Yellow: "\x1b[33m",
    Blue: "\x1b[34m",
    Magenta: "\x1b[35m"
};

var funcNames = ["info", "log", "warn", "error"];
var colors = [colorSet.Green, colorSet.Blue, colorSet.Yellow, colorSet.Red];

for (var i = 0; i < funcNames.length; i++) {
    let funcName = funcNames[i];
    let color = colors[i];
    let oldFunc = console[funcName];
    console[funcName] = function () {
        var args = Array.prototype.slice.call(arguments);
        if (args.length) {
            args = [color + args[0]].concat(args.slice(1), colorSet.Reset);
        }
        oldFunc.apply(null, args);
    };
}

// Test:
console.info("Info is green.");
console.log("Log is blue.");
console.warn("Warn is orange.");
console.error("Error is red.");
console.info("--------------------");
console.info("Formatting works as well. The number = %d", 123);

根据这个文档，你可以根据输出的数据类型改变颜色:

// you'll need the util module
var util = require('util');

// let's look at the defaults: 
util.inspect.styles

{ special: 'cyan',
  number: 'yellow',
  boolean: 'yellow',
  undefined: 'grey',
  null: 'bold',
  string: 'green',
  date: 'magenta',
  regexp: 'red' }

// what are the predefined colors?
util.inspect.colors

{ bold: [ 1, 22 ],
  italic: [ 3, 23 ],
  underline: [ 4, 24 ],
  inverse: [ 7, 27 ],
  white: [ 37, 39 ],
  grey: [ 90, 39 ],
  black: [ 30, 39 ],
  blue: [ 34, 39 ],
  cyan: [ 36, 39 ],
  green: [ 32, 39 ],
  magenta: [ 35, 39 ],
  red: [ 31, 39 ],
  yellow: [ 33, 39 ] }

这些似乎是ANSI SGR转义码，其中第一个数字是在输出之前发出的代码，第二个数字是在输出之后发出的代码。因此，如果我们看一下维基百科上的ANSI SGR代码图表，你会发现大多数代码都以数字30-37开始设置前景色，以39结束重置为默认前景色。

我不喜欢的一点是有些颜色太深了。特别是日期。继续，在控制台中尝试new Date()。深色洋红色加黑色真的很难辨认。让我们把它换成浅洋红色。

// first define a new color
util.inspect.colors.lightmagenta = [95,39];

// now assign it to the output for date types
util.inspect.styles.date = 'lightmagenta';

现在，当您尝试new Date()时，输出的可读性大大提高。

如果你想在启动node时自动设置颜色，创建一个脚本来启动repl，就像这样:

// set your colors however desired
var util = require('util');
util.inspect.colors.lightmagenta = [95,39];
util.inspect.styles.date = 'lightmagenta';

// start the repl    
require('repl').start({});

保存这个文件(例如init.js)，然后运行node.exe init.js。它将设置颜色并启动node.js命令提示符。
