This is a completely dark theme for the Jupyter Notebook interface.
Jupyter includes iPython 4 as its default kernel (which, confusingly, supports both Python 2.x and 3.x).
Since the iPython 3 to 4 transition, it has gained better support for other interpreters like R and Ruby. It is possible to upgrade iPython 2 or 3 to Jupyter + iPython 4.
Source code coloring is based on the Twilight theme for Textmate. Print preview output for notebooks retains a white background with printable foreground colors.
To install this theme, copy or symlink custom.css into ~/.jupyter/custom/
cd ~/.jupyter/custom/
(create that directory if it doesn't exist: mkdir )
vi custom.css
Then, whenever you run jupyter notebook, iruby notebook, etc. it will use this theme.
most of the coloring information can be modified after line 300.
