Hello,
you can change it with CSS in this file: wp-content\themes\jomelle\css\the-creator.css
, find this code (it is on line 163):
.tcvpb_section_tc header h2:after {
display: block;
content: "";
width: 38px;
height: 2px;
background: #f1501a;
position: absolute;
left: 50%;
margin-left: -19px;
bottom: -22px;
}
you will need to change background color and that will work.
Thank you for pointing that out to us.
We will fix it as soon as possible and update will be released.
Best Regards
