Good evening Maanit and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the colors not being to your liking.
I would love to help you with this topic.
There are a couple of ways to approach this:
- Make sure to check your settings under Events -> Settings -> Display and make sure that the “Full styles” option is selected
- Take a look at Appearance > Customize > the Events Calendar to see if you can’t find a setting that does what you are looking for
- If none of that works, you can simply try adding a CSS rule to your theme’s style.css file or in your Custom CSS metabox.
For that last part, I would need to have an example URL to help you out.
Let me know how that goes.
Best regards,
Geoff B.
