woodmart_get_dropdown_param function throws deprecation notice

Hi, when I open in WPbakery extra menu list element settings and click label color drop-down following PHP notice is thrown:

PHP Deprecated:  Invalid characters passed for attempted conversion, these have been ignored in /public_html/wp-content/plugins/woocommerce/includes/wc-formatting-functions.php on line 915

Apparently, it happens because primary colors are set in Woodmart as RGB and WooCommerce function wc_light_or_dark called in Woodmart function woodmart_get_dropdown_param expects HEX.
