Theme setting variable

Been using same theme for years but one thing annoys me and that is very little contrast in below scenario (picture). Which theme variable do I need to change to get that white background darker or maybe better how do I get the white text after “service” darker (without affecting other views). Difficult to find complete documentation on this.

Try these:

  codemirror-property: 
  codemirror-string: 
  codemirror-keyword: 
  codemirror-number: 
  codemirror-comment: 
  markdown-code-background-color:  

markdown-code-background-color:

Allows me to indeed change the background but the others (codemirror-property: etc) do not have an impact on the text (eg the text after service: in above example). Could it be another variable?

That could just be primary-text-color
