A cored, fixed, documented and optimized version of the popular colors.js. Can be
used as a drop-in replacement, also works correctly in the browser, provides a CSS mode and has been compiled through
Closure Compiler using advanced optimizations. Additionally, nearly every issue and pull request on the original has
been incorporated.

Installation

npm install colour

Usage

This package extends the global String prototype with additional getters that apply terminal colors to your texts.
Available styles are:

• Emphasis: bold, italic, underline, inverse
• Colors: yellow, cyan, white, magenta, green, red, grey, blue
• Sequencers: rainbow, zebra, random

Example

 var colour = require('colour');
console.log('hello'.green); // outputs green text
console.log('i like cake and pies'.underline.red) // outputs red underlined text
console.log('inverse the color'.inverse); // inverses the color
console.log('OMG Rainbows!'.rainbow); // rainbow (ignores spaces)

Or: As a drop-in replacement for colors

 var /* just name it */ colors = require('colour');
...

Custom themes

Its also possible to define your own themes by creating new getters on the String object. Example:

 var colour = require('colour');
colour.setTheme({
  silly: 'rainbow',
  input: 'grey',
  verbose: 'cyan',
  prompt: 'grey',
  info: 'green',
  data: 'grey',
  help: 'cyan',
  warn: ['yellow', 'underline'], // Applies two styles at once
  debug: 'blue',
  error: 'red bold' // Again, two styles
});

console.log("this is an error".error); // outputs bold red text
console.log("this is a warning".warn); // outputs underlined yellow text

console.log(colour.green("this is green")); // Alternatively

Console, browser and browser-css mode

 var colour = require('colour');
...
colour.mode = 'none'; // No colors at all
colour.mode = 'console'; // Adds terminal colors (default on node.js)
colour.mode = 'browser'; // Adds HTML colors (default in browsers)
colour.mode = 'browser-css'; // Adds special CSS (see examples/example.css)

Uninstalling / reinstalling on the global scope

If you have a reason to use a fresh String prototype in your application, you may also revert all extensions made.

 var colour = require('colour');
...
colour.uninstall(); // Removes all custom properties from the String prototype
...
colour.install(); // Re-installs them
...
