Removing 'more colors' button in MCE

Hi All,

I use the following snippet to remove some options from Tiny MCE to protect the design from my client:

function make_mce_custom( $init ) {

	$init['theme_advanced_blockformats'] = 'p,h6,h5,h4,h3,h2,h1';
	$init['theme_advanced_text_colors'] = 'FFFFFF,AAAAAA,000000,522F91,EC008C,00AEEF';
	$init['theme_advanced_disable'] = 'underline,justifyfull,wp_more,indent,outdent,forecolor';

	return $init;
}

add_filter('tiny_mce_before_init', 'make_mce_custom');

However, what I want is to add 6 colors they can choose from, but I want to hide the ‘more color’ button which gives the colorpicker. Is this possible?
