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);
        }
    });
}

node-colorify

提供功能打印文本的颜色，也做文本格式，如粗体，闪烁等。

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。

颜色参考

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"

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

}

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"

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。
