Syntax Highlighting Defaults?

For example on this github.io page, in the syntax highlighting in the code blocks

-T4 -n -sC -sV -Pn -p- is highlighted a pale orange
"touch " . $_GET['democ'] . '.txt' or any thing in quotes is highlighted a poopy green

I can’t seem to change the syntax highlighting for syntax in those formats. I’ve played around with css file and looked at the variable definitions but none of them affect the syntax highlighting for those sections of code. Any idea how I can change it?

You can check its source code for more information, since it is open. It doesn’t seem to have any customization regarding its syntax highlighter.

I’m using Jekyll Chirpy and their wiki says to use a .scss file to change syntax highlight

I can change the highlighting for some variables using one of these themes but can’t specifically change

-T4 -n -sC -sV -Pn -p- is highlighted a pale orange
"touch " . $_GET['democ'] . '.txt' or any thing in quotes that is highlighted
