You can use any Vim color scheme in Vem. To install a new color scheme follow two steps:
Copy the color scheme to the Vem configuration directory:
If the color scheme is a single <color-scheme>.vim file, then you need to copy it to ~/.config/vem/colors/.
If the color scheme is distributed as a plugin (for example, if it is a repository containing a colors/ directory inside), then you need to install it as any other plugin by copying it to ~/.config/vem/pack/plugins/start/.
Activate it in your vemrc file:
After, the color scheme is added to your configuration, include the following line to your vemrc file:
where <color-scheme> is the name of the file of the color scheme without the .vim extension.
