to my shame i did not know how to customize the nmtui default colors (for the sake of my own health and mental stability). after reading a bit, i found out it uses the so-called newt backend with the whiptail app.
long story short... turns out it reads some of the env variables for that backend to setup the colors (if you're interested, here's where this happens in the code).
so you can simply set these env variables before calling nmtui. here's a combination i came up with:
NEWT_COLORS='root=black,black;window=black,black;border=white,black;listbox=white,black;label=blue,black;checkbox=red,black;title=green,black;button=white,red;actsellistbox=white,red;actlistbox=white,gray;compactbutton=white,gray;actcheckbox=white,blue;entry=lightgray,black;textbox=blue,black' nmtui
enjoy and keep your eyes healthy!
Please don't use "rape" as a casual negative verb, there are better, more accurate words to use that don't needlessly reference SA.
i really apologize if the use of that word was perceived as offensive, that was obviously not my intent. i'm usually quite straightforward in picking words (i come from a completely different culture, where sexual assaults are extremely uncommon).
PS. for the context of others reading this comment, the original title of this post was: "nmtui that does not rape your eyes."
Thank you, OP.
It is more likely that you are just not aware of it.
What culture is that? I wasn't aware such a thing existed.
Probably a Scandinavian country if I had to guess.
Thanks!
