Result

Long time ago i've faced annoying issue with colors under screen/tmux.
Googling a lot i've found that i'm not alone with this.
In short, colors in apps under screen (im active fan of this app) are significantly broken. I've changed color schemes, terminal settings like

term "screen-256color"
term "xterm-256color"

, hacks of terminal files ..and so on. That issue killed a lot of time and nervous. Solution, as usual, was simple and even "stupid". I'm not sure how that was found, i was thinking about same thing but can't reverse that to understand what was happening.
Finally solution was found here: https://github.com/busyloop/lolcat/issues/117 (thanks a LOT btw)
Fix in my case looks like this:

# vim ~/.bash_aliases OR vim ~/.profile OR ENEN vim ~/.bashrc
# force cleanup of this var
export COLORTERM=

Screenshots with description of issue below

No screen, simple xfce terminal - OK


Broken colors, mc loaded under screen


That painfull pre-set variable


vim ~/.bash_aliases


Saved, restarted terminal, run screen, run mc - colors fixed.
