Hi David,
Thanks for reaching out! While our WordPress Customizer options don’t yet include selectors for the day-of-the-week header, you can make changes to this area using CSS instead. This Knowledgebase article provides a bit more information on how you can use CSS to change the look and feel of any element on any of your calendar views! For a quick change to your day-of-the-week header, simply navigate to Appearance > Customize in your WordPress admin, click the Additional CSS option from the sidebar menu, and paste the following CSS (saving your changes once you’ve finished):
.tribe-events-calendar thead th {
background-color: #000000;
color: #FFFFFF;
}
In this example, the background color is represented by the hex value #000000 (which displays as solid black), while the text color is designated as hex value #FFFFFF (solid white). You can change these colors to anything you’d like–this color picker will give you the hex value (beginning in #) for any color you select.
I hope that helps! Thanks again, and let us know if you should have any other questions! 🙂
