Adding Color Field within a Custom Form for Layout Builder

Hello,

I am trying to add in a Color Field to display the Widget Boxes and while looking through the code, I just cannot get it to display. Here is my code that I have that I'm trying to add the field for:

$form['bg_colors'] = [
              #type' => 'color_field_type',
              #title' => $this->t('Background Colors'),
              #default_value' => $this->configuration['bg_colors'],
              #description' => $this->t('Choose a background color for the whole layout.'),
            ];

But this doesn't render or show anything. If I change the '#type' variable to 'color', I get an HTML5 Color select box, but that will not work for me, as I need to limit the selection of colors to some very specific colors.

How can I implement the Color Field programmatically?
