Add another Theme
Themes that you use often can be included by simply adding the theme name to the
dotspacemacs-themes list. The first theme in the list is loaded when Spacemacs starts.
dotspacemacs-themes '(spacemacs-dark spacemacs-light cyberpunk)
The order of the themes in the list is the order Spacemacs will cycle through those themes,
SPC T n for the next theme and
SPC T p for the previous theme.
The first time you select a theme it will be automatically downloaded, installed and used. This may take a few seconds to load.
There are many themes available for Spacemacs that will change the colours of text, background, etc.
Here is an example of the cyberpunk theme, familiar to those who use to use Emacs Live.
