我真的很喜欢@Daniel的回答，但是console.log{color}函数的工作方式与常规的console.log不同。我做了一些更改，现在所有参数的新函数将被传递到console.log(以及颜色代码)。

const _colors = {
    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",

    BgBlack : "\x1b[40m",
    BgRed : "\x1b[41m",
    BgGreen : "\x1b[42m",
    BgYellow : "\x1b[43m",
    BgBlue : "\x1b[44m",
    BgMagenta : "\x1b[45m",
    BgCyan : "\x1b[46m",
    BgWhite : "\x1b[47m",
};

const enableColorLogging = function(){
    Object.keys(_colors).forEach(key => {
        console['log' + key] = function(){
            return console.log(_colors[key], ...arguments, _colors.Reset);
        }
    });
}

Sindre Sorhus设计的这个图书馆是目前最好的:

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。

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。

这适用于(我所知道的)Node控制台。

该包是快捷方式，您可以使用此命令安装它。 Const short = require('@testgrandma/shortcuts');

您可以执行两个命令来更改颜色。它是RGB颜色和Hex颜色short.colorRGB(r,g,b);

short.colorhex(十六进制);

你可以执行console.log(short.colorhex('d50000') + 'This is red!');

包裹可以在这里找到。

https://www.npmjs.com/package/@testgrandma/shortcuts

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:
