Rather than displaying the attribute name I would like to display it's description. Is this possible?

function woo_specifications_product_tab_content() {

// The new tab content
global $product;
echo '<h2>Specifications</h2>';
echo $product->get_description();
echo $product->get_attribute( 'colour-code' ); ///I WANT THE COLOUR-CODE DESCRIPTION RATHER THAN THE JUST THE COLOUR CODE. 
}
