Hi there,

Thank you for your message.

These button colors are intended to be linked to the button color settings in the theme customizer. Unfortunately, it seems this feature isn’t working as expected at the moment. We’re working on a fix and will include it in the next theme update. We apologize for the inconvenience.

For now, you can change this by copy/paste the following CSS code to Appearance -> Customize -> Additional CSS:

/* Change single gallery page pagination button color */
.project-navigation a[rel="prev"], 
.project-navigation a[rel="next"] {
	background-colo: #f0b443;
}
.project-navigation a[rel="prev"]:hover, 
.project-navigation a[rel="next"]:hover {
	background-colo: #f0b443;
}

Hope this helps, let me know if you have any questions.
