Atom's One themes for GNOME Terminal
Here are One Dark and One Light themes for GNOME Terminal (available on Ubuntu, Fedora, Elementary OS, etc). These themes use color palette from original Atom's One Dark and One Light syntax theme.
For installation just execute desired command below. Be careful, terminal will be closed after install.
One Dark
bash -c "$(curl -fsSL https://raw.githubusercontent.com/denysdovhan/gnome-terminal-one/master/one-dark.sh)"
One Light
bash -c "$(curl -fsSL https://raw.githubusercontent.com/denysdovhan/gnome-terminal-one/master/one-light.sh)"
I recommend to use Inconsolata or Fira Mono fonts for better compatibility with Atom Editor.
