URGENT Problem Wooocommerce swatches

Hello

I have 2 issues regarding the plugin version PRO woocoommerce PRO version

1/ our code color are code HEX but inside the plugin code colors are RGA : we have 400 colors : how can we do ?

2/We have thousands of products with 400 color codes like Black (color code: 000000) We are using Woocommerce CSV suite import for uploading products from CSV files. We didn’t figure out the option to upload color code for variation products automatically via CSV file.

Please let us know the Product mapping solution for it.
