Cannot replace default color palette

I would like to replace default WordPress color palette, displayed below Astra theme palette, but I failed even though I used this code simple code, which looks to be fine:

function my_theme_add_new_features() {
    // The new colors we are going to add
    $newColorPalette = [
        [
            'name' => esc_attr__('Magenta', 'default'),
            'slug' => 'magenta',
            'color' => '#ff00ff',
        ],
        [
            'name' => esc_attr__('Cyan', 'default'),
            'slug' => 'cyan',
            'color' => '#00ffff',
        ],
    ];
    // Apply the color palette containing the original colors and 2 new colors:
    add_theme_support( 'editor-color-palette', $newColorPalette);
}
add_action( 'after_setup_theme', 'my_theme_add_new_features', 30 );

I am attaching a picture of which palette I mean. The first palette from Astra is fine, I would like to change the colors of the second palette, as the default WordPress palette.

Thank you for your help!
