I tried that, and it works as it should in the TwentySixteen theme. So, it would seem it is an issue with our theme.

When I inspect with the web dev tools in firefox it shows this:

.tribe-events-category-vtr h2.tribe-events-list-event-title.entry-title a, .tribe-events-category-vtr h2.tribe-events-list-event-title a, .tribe-events-category-vtr h3.tribe-events-list-event-title a, .tribe-event-featured .tribe-events-category-vtr h3.tribe-events-list-event-title a, .tribe-events-list .tribe-events-loop .tribe-event-featured.tribe-events-category-vtr h3.tribe-events-list-event-title a .tribe-events-shortcode .tribe-events-month table .type-tribe_events.tribe-events-category-vtr, .tribe-events-list-widget li.tribe-events-category-vtr a:link, .tribe-events-list-widget li.tribe-events-category-vtr a:visited, li.tribe-events-list-widget-events.tribe-events-category-vtr a:link, li.tribe-events-list-widget-events.tribe-events-category-vtr a:visited, .tribe-events-list .tribe-events-loop .tribe-event-featured.tribe-events-category-vtr h3.tribe-events-list-event-title a:hover, #tribe-events-content table.tribe-events-calendar .type-tribe_events.tribe-events-category-vtr.tribe-event-featured h3.tribe-events-month-event-title a:hover, .teccc-legend li.tribe_events_cat-vtr a, .tribe-common article.tribe_events_cat-vtr h3 a, .tribe-common article.tribe_events_cat-vtr h3 a:link, .tribe-common article.tribe_events_cat-vtr h3 a:visited, article.tribe-events-calendar-month__multiday-event.tribe_events_cat-vtr h3, #tribe-events-content table.tribe-events-calendar .tribe-event-featured.tribe-events-category-vtr .tribe-events-month-event-title a, .teccc-legend li.tribe-events-category-vtr a, .tribe-events-calendar .tribe-events-category-vtr a, #tribe-events-content .teccc-legend li.tribe-events-category-vtr a, #tribe-events-content .tribe-events-calendar .tribe-events-category-vtr a, .type-tribe_events.tribe-events-category-vtr h2 a, .tribe-events-category-vtr > div.hentry.vevent > h3.entry-title a, .tribe-events-mobile.tribe-events-category-vtr h4 a {
  color: #fff;
  text-decoration: none;
}

Even though we have the category color in the plugin set to: #a7141d

Unsure if this helps at all, but it seems to be calling out this part superficially: article.tribe-events-calendar-month__multiday-event.tribe_events_cat-vtr h3 in the above code.
