Install this color scheme using your preferred Vim plugin manager, then add the following to your (n)vim configuration file:
set background=dark
set termguicolors
colorscheme deep-space
If your terminal supports italics, add:
let g:deepspace_italics=1
To use the included vim-airline theme:
let g:airline_theme='deep_space'
I've not cared about lightline as I don't use it
