Hi @eggbird
Thanks for reaching out. Let me help you with this one.
Could you try adding the following CSS to Appearance > Customize > Additional CSS, and see if that helps:
.post-type-archive-tribe_events .tribe-events button.tribe-events-c-top-bar__datepicker-button,
.post-type-archive-tribe_events .tribe-events .tribe-events-calendar-list__event-datetime,
.post-type-archive-tribe_events .tribe-events .tribe-events-calendar-list__event-title-link,
.post-type-archive-tribe_events .tribe-common .tribe-common-b2,
.post-type-archive-tribe_events .tribe-events .tribe-events-calendar-list__event-date-tag-weekday,
.post-type-archive-tribe_events .tribe-common .tribe-common-h5,
.post-type-archive-tribe_events .tribe-common .tribe-common-h6,
.post-type-archive-tribe_events .tribe-events .tribe-events-calendar-month__header-column-title,
.post-type-archive-tribe_events .tribe-events .tribe-events-c-messages__message-list-item-link{
color: #fff !important;
}
Let me know how it goes.
