I notice that when I change the button colours in my Theme settings, they change to my chosen colour. Once I click “Publish”, they revert back to black / grey. Any help would be appreciated. Thank you.
The customization options are available inside the “style” tab of the widget options in elementor:
If you are not using Elementor, maybe it’s better to create a custom CSS to change the color, then add the snippet to Appearance > Customize > Additional CSS. If that’s the case, please send us a link to your website and the color you need. We can generate a CSS snippet for you.
