Hello,

You have not configured anything in Advanced Typography. That is why no change.

1. Add this code to the Theme Settings > Custom CSS:

body .title-wrapper .title-subtitle {
    font-size: 13px;
   color:red;
}
body .title-wrapper  .woodmart-title-container {
  color:blue;
}
.woodmart-products-tabs.tabs-design-default .products-tabs-title .tab-label{
color:red;
} 

Change the color as per your needs.

In order to change the color of the Tabs enter the element and find the option http://prntscr.com/m5jmwg

Best Regards
