How do I pass a value from a subscriber.php class to my html.twig file?

[hasan.h]

I have created a Subscriber.php file that assigns values from config.xml file to the css variables using the following tutorial:

Add SCSS variables

I want to pass these variables to inline css in my index.html.twig file. Can someone help me out as to how I can get this done?

Passing variables from PHP to Twig templates is not that hard. I have a tutorial about this on my Shopware blog: How to get the data from PHP to the Twig template - Shopwarian.com. It also includes an example with a subscriber, so I think that is what you are looking for.

I tried searching via ctrl+f in the dump but the variables are still not there
This is my index.html.twig file for reference:
