Change color of heading, subheading and title

What do you need help with?

Dear Anytype Community.
for two weeks I use Anytype now and it transformed my way of storing information, files, images and booksmarks in a way I never dreamed possible.

I have one question:
How can I permanently assign a specific color to title, heading and subheading in any document.
I use the dark theme and all headings types are white.
I read that you can adjust the theme.css and ask Chatgpt in varior methods to write me the necessary codes, even uploaded some code lines and pictures from the developer console. But nothing seems to work. The only color I could change was the title color of the document itself.
I also tried some ready to download css files from github but they did not change anything.
Of course “apply custom Css” is activated.

Thank you for your help.
Stefan
