Hello Christine,
Thanks for using our plugins and welcome to the forums!
Thanks for your question. We usually don’t support customizations but since this is an easy one I can help you out with this.
You can modify the background color of the tickets table with a little CSS code. Just paste the following snippet into your theme’s style.css file. (Go to Appearance > Editor, this should open the style.css file by default.)
.tribe-events-style-full .tribe-events-tickets tr {
background-color: #ff0000;
}
This will change the background color of all the rows of the ticket table to red. Of course you can adjust the color based on your need.
Let me know if this helps.
Cheers,
Andras
