Howdy runekjensen,
The heading color is specified within tribe-events-theme.min.css. Since it is a minified file a line number would be useless. To override the heading color I would use the following code to make it black:
body #tribe-events-content .tribe-events-tooltip h4{ color:#000; }
The event background color is specified in tribe-events-pro-theme.css on line 30. I’d use the following rule to override:
body .tribe-grid-allday .hentry.vevent > div,
body .tribe-grid-body div[id*="tribe-events-event-"] .hentry.vevent,
body .tribe-grid-allday .hentry.vevent > div:hover,
body .tribe-grid-body div[id*="tribe-events-event-"] .hentry.vevent:hover {
background-color: #000;
background-color: rgba(0, 0, 0, .75);
border-color: #333;
}
Does that help? Please let us know. Thanks!
