I am a big fan of switching themes, light theme for daytime/bright conditions and dark one for evening/night/darker environment.
There are many different emacs themes available (two of them are developed and supported by me).
How to find themes?
M-x package-list-packages and then search (C-s) for the word theme.

I would highly recommend installing all sets of themes of his production and this might be all as there is enough choice for everyday life. All of them are available via melpa:
