Have you checked the color schemes in Konsole itself? For the best results, select “Linux console”, and then you can also make the terminal translucent ─ best used in combination with the blur effect, of course.
It appears if I use: alias ls='ls --color=auto'
in my .zshrc file, I get the desired change.
Editing a ~/.dircolors file the refine the colors then gives me what I’m looking for.
