Directory highlighted in terminal
The (background and foreground) color of the folder Qt in your ls output is determined by the last two pairs in your ls color scheme: ExFxBxDxCxegedabagacad because it's world writable.

        ↑↑
        |but no sticky bit (a sticky bit would be indicated by a "t")
        world writeable


The last (=11th) pair colorizes directories writable to others but without sticky bit. The color scheme as indicated by your LSCOLORS env variable is a=black foreground and d=brown background. To set it to your default directory color simply change it to ...Ex.



Applying the posted color scheme (PS1 &amp; LSCOLORS and assuming user Davos Doe = user Hung Hoang, who posted the scheme as well as the ls output in an answer, which got deleted and is visible to users with a reputation of ≥ 10,000 only) in a default Terminal shell I get almost completely different color effects though.
