Finding the correct place to be to the change theme colour

Hello everybody

I have been having problems trying to locate the exact correct place to change the colour for 2 particular things in the theme, The background colour on the left for the selected folder and the font colour on the right. Could someone kindly point me to the specific places I need to be for both items I've highlighted in the screenshot. Thank you so much in advance.

Assuming Opus 12:

  • Make sure Preferences / Display / Options / Visual styles override file selection colors is off.
  • Preferences / Display / Colors and Fonts / File group header
  • Preferences / Display / Colors and Fonts / Folder tree

Leo, thank you very much, I appreciate your quick response.
