Hi Heather,
Thanks for reaching out!
As a first step, I would recommend adjusting the “Default stylesheet used for events templates” and “Events template” settings under Events > Settings > Display. These affect how much events pages inherit their styling from the theme.
You can also try changing the settings under Appearance > Customize > The Events Calendar. If this doesn’t get you what you need, then you may need to add some CSS to get the colors exactly right.
We are limited in the amount of support that we can provide for customizations, but if you get stuck or have any questions, please let me know – I’ll be happy to try to point you in the right direction!
Thanks,
Jennifer
