Hey Robert,
Thank you for reaching out to us! You can change the background color of the week’s row in month view by adding the following code in your style.css file:
.tribe-events-calendar thead th, .tribe-events-grid .tribe-grid-header .tribe-grid-content-wrap .column, .tribe-grid-header {
background-color: grey !important;
}
In this example the color with be changed to grey. I’ve tested this code on your site and it worked as expected.
I hope this helps! Let me know if you need anything else and have a great week!
Regards,
Patricia
