Your termite config ~/.config/termite/config has been split into two other
configs (~/.config/termite/option && ~/.config/termite/color/default) which you
should use to edit your settings from now on because the original file
(~/.config/termite/config) will be overwrite when using the color command

The ~/.config/termite/color/default stores info in the color section and the
~/.config/termite/option stores the rest of the config (options and hints
section)."
