Supports `-g` flag and strips all others (I expect people to try other flags even though they don't exist)

colors.js

'use strict';
module.exports = function(bot, IO) {
	function color ( args ) {
		var outType, base, param;
		
		if ( args.match( /-g/ ) ) { //the only flag for this is g(gradient)
			outType = 'gradient=';
		} else outType = 'color=';
		
		base = 'http://jhawins.tk/colors.php?';
		
		param = args.toLowerCase()
			.replace( /-[a-z]*/, '' )//strip all flags
			.match( /([a-z0-9]+)+/g );
	
		args.directreply( base + outType + param + '#.png' );
	}
	
	bot.addCommand({
		name : 'color',
		permissions : {
			del : 'NONE'
		},
	
		description : 'Displays the' +
			'color(s) passed in as RGB, hexadecimal' +
			'or hex-shorthand or standard color names' +
			'(if it works in CSS it should work here). ' +
			' `/color color0[ color1[ ...]]`' +
			'use -g for gradient'
	};
};
