Hello, @SC,
Unfortunately, there is no such option in our theme to Customize in terms of colors the Specific Category, This requires extra Customization.
You can achieve it using Custom CSS, but it will be a bit tricky.
You have to inspect the particular category and then copy the particular category class: https://postimg.cc/64vYVvj0 and then set the Custom CSS for that particular class and add it under XStore >> Theme Settings >> Theme Custom CSS >> Global Custom CSS.
