Don't display paragraph block colors if support is disabled and palette is empty array

[maxxwv]

Issue Overview

As of now we can opt to turn off the custom color picker using 'disable-custom-colors' theme support option, as well as being able to define specific color chips to override the defaults. This is great, and thank you! However, this:

add_theme_support('editor-color-palette', array(
	'colors' => [], //also tried false, just in case...
));
add_theme_support('disable-custom-colors');

yields this:

Seems to me from an user experience perspective it'd be better not to display the option areas at all if the editor can't actually make a choice there.

Hi,

Your code will actually not work as you are passing an array argument to add_theme_support( 'editor-color-palette', $argument ), which is not possible currently (I've logged an issue for that: #6425).

If you want to get rid of all the colors, this seems to work for me (using Gutenberg 2.6.0):

add_theme_support( 'editor-color-palette' );
add_theme_support( 'disable-custom-colors' );

However, please note that this will not remove the color option areas from Gutenberg block settings.
And also feels like a bug in declaring the theme support for color palette (→ to whom this may concern).

Regards,

Oliver
