sorry bro, just wanted to help

Hi there!
Try to delete reCAPTCHA (v3) integration in settings in Contact Form 7 integration menu (you should see blank fields after you do that). And then install Math Captcha instead, for example.
Thank worked for me!

OR find the standard css for the plugin (default installation path):
../wp-content/plugins/variation-swatches-for-woocommerce/assets/css/frontend.css

find in .tawcvs-swatches .swatch block, at line 29
change
opacity: 0.5;
to
opacity: 1;
