## Basic usage:
Output colored text:
```js
var color = require('colors-cli')
console.log( color.red('hello') )
```
Best way is to predefine needed stylings and then use it:
```js
var color = require('colors-cli/safe')
var error = color.red.bold;
var warn = color.yellow;
var notice = color.blue;
console.log(error('Error!'));
console.log(warn('Warning'));
console.log(notice('Notice'));
```
Styles can be mixed:
```js
var color = require('colors-cli/safe')
console.log('=>', color.red.bold.underline('hello') )
console.log('=>', color.magenta_bt.underline('hello ' + color.blue_bt('wo' + color.yellow_bt.magenta_bbt('r') + 'ld') + ' !!!!'));
console.log('=>', color.magenta_bt.underline('hello ' + color.blue_bt('wo' + color.yellow_bt.magenta_bbt('r'))));
console.log('=>', color.magenta_bt.underline('hello ' + color.blue_bt('world') + ' !!!!' + color.yellow('kenny') + ' wong' ));
var color = require('colors-cli/safe')
require('colors-cli/toxic')
console.log('=> ' + color.underline('$ ' + 'npm'.magenta.underline + ' install'.yellow.underline + ' colors-cli --save-dev'));
```
```js
require('colors-cli/toxic')
console.log( 'hello'.green );
console.log( 'hello'.green.black_b.underline );
console.log('=> $'.green + ' npm '.magenta + 'install '.yellow + 'colors-cli'.cyan + ' --save-dev');
```
