Hi, regarding Drupal\color_field\Plugin\Field\FieldFormatter\ColorFieldFormatterText::getColorFormat():
This is 7.4 compatible:

/**
 * This function is used to get the color format.
 *
 * @param string|null $format
 *   Format is of string type.
 *
 * @return array|\Drupal\Component\Render\MarkupInterface
 *   Returns array or string.
 */
protected function getColorFormat(?string $format = NULL) {
    $formats = [];
    $formats['hex'] = $this->t('Hex triplet');
    $formats['rgb'] = $this->t('RGB Decimal');

    if ($format !== null) {
        return [$format => $formats[$format]];
    }

    return $formats;
}
