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'));

require('colors-cli/toxic')
