To change the standard color scheme of Midnight Commander, open the file:
~/.config/mc/ini
or if 1 item did not work
~/.mc/ini
Create a section there with something like this.
[Colors] base_color=lightgray,blue:normal=blue,default:selected=white,brightblue:marked=yellow,default:markselect=yellow,gray:directory=brightblue,default:executable=brightgreen,default:link=cyan,default:device=brightmagenta,default:special=lightgray,default:errors=red,default:reverse=green,default:gauge=green,default:input=white,gray:dnormal=green,gray:dfocus=brightgreen,gray:dhotnormal=cyan,gray:dhotfocus=brightcyan,gray:menu=green,default:menuhot=cyan,default:menusel=green,gray:menuhotsel=cyan,default:helpnormal=cyan,default:editnormal=green,default:editbold=blue,default:editmarked=gray,blue:stalelink=red,default
And yes, here you have some strange terminal emulator from IDE. Take something normal like Konsole, rxvt, Yakuake.
The code above creates a new color scheme directly in the configuration file. However, there are some more ready-made schemes. To list and edit them:
ls /usr/local/share/mc/skins
To install, add an option to the [Midnight Commander] main section:
skin=%название темы без расширения ini%
Or run mc with key S
mc -S skinname
