What would be the best way to save a background choice to cookie in IPS V4?

I'm thinking of supplying our users the choice of background but I would need this to be saved to cookie, anyone know the best way to achieve this in IPS V4?

Anyone any ideas? Would appreciate the help.

In PHP: \IPS\Request::i()->setCookie();

	/**
	 * Set a cookie
	 *
	 * @param	string				$name		Name
	 * @param	mixed				$value		Value
	 * @param	\IPS\DateTime|null	$expire		Expiration date, or NULL for on session end
	 * @param	bool				$httpOnly	When TRUE the cookie will be made accessible only through the HTTP protocol
	 * @param	string|null			$domain		Domain to set to. If NULL, will be detected automatically.
	 * @param	string|null			$path		Path to set to. If NULL, will be detected automatically.
	 * @return	bool
	 */
	public function setCookie( $name, $value, $expire=NULL, $httpOnly=TRUE, $domain=NULL, $path=NULL )

 

In JavaScript: ips.utils.cookie.set()

		/**
		 * Set a cookie value
		 *
		 * @param	{string} 	cookieKey 	Key to set
		 * @param 	{mixed} 	value 		Value to set in this cookie
		 * @param 	{boolean} 	sticky 		Whether to make this a long-lasting cookie
		 * @returns {void}
		 */
		set = function( cookieKey, value, sticky )
