What is the meaning of each highlight?

[SubLemon]

I have ST3. I am struggling to find the meaning of each color highlight in ST3. Is there a guide to it? Can you customize the colors?

Syntax highlighting is determined though a concept called “scoping”, where the file is parsed using regular expressions that assing certain scopes to text segments. These scopes can be nested.

Then, formatting is applied to the file using “scope selectors”, which follow a deterministic algorithm based on prioritization and implicit wild cards.

Responsible for the first part are “syntax definitions”: docs.sublimetext.info/en/latest/ … xdefs.html
