Global Colors - Snippet does not work

Hi
just applied this code as a Code Snippet:
add_action( ‘after_setup_theme’, function() {
add_theme_support( ‘editor-color-palette’, array(
array(
‘name’ => __( ‘DBlue’ ),
‘slug’ => ‘blue’,
‘color’ => ‘#2F2FA2’,
),
array(
‘name’ => __( ‘Green’ ),
‘slug’ => ‘green’,
‘color’ => ‘#58AD69’,
),
array(
‘name’ => __( ‘Orange’ ),
‘slug’ => ‘orange’,
‘color’ => ‘#FFBC49’,
),
array(
‘name’ => __( ‘Red’ ),
‘slug’ => ‘red’,
‘color’ => ‘#E2574C’,
),
) );
} );

but in Block Editor the default colors are still there, as you can see here:

Please help, thanks in advance
