Sass - can users compile?

Question

Sass

The question may seem rather vague.
There is a template with an admin panel and primary colors, let's say main_color_1 and main_color_2.
These primary colors are used throughout the site, in a wide variety of elements.
Using Sass idealizes editing if I use the $main_color_1 and $main_color_2 variables. But there is one but.
In the template admin panel, the user must set any color for main_color_1 and main_color_2.
How to do it in Sass if it needs to be compiled?
Is this even possible or are there other options?

Answer 1

If I understand the task correctly, your question can be shortened to "how to pass sass variables when compiling".
You can find the following answer to such a question: stackoverflow.com/questions/31148803/injecting-var...
It is long, I did not master it.
I would just save the value of the variables to a file (_variables.sass), and then run the sass compilation with this file included.

Answer 2

It needs to be implemented via JavaScript.
