## 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');

```
