I'm typically running
emacs -nw: problem is that Emacs overrides terminal (bash) color scheme and uses it's own default one which is in some cases unreadable.
I would like emacs to use default colors which are defined in my terminal "app". I recently updated to Ubuntu 16.04 and this is when this started happening.
Was looking, couldn't find an answer anywhere.
(setq frame-background-mode 'dark)
seems to fix readability problem, however it's not 100% what I would like
