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');

如果你想改变颜色直接自己没有模块尝试

console.log('\x1b[36m', 'sometext' ,'\x1b[0m');

先\x1b[36m改变颜色为36，然后回到终端颜色0。

下面是ANSI颜色代码列表

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。

(感谢loganfsmyth对repl想法的回答。)

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。

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"

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。
