Install using your favourite package manager, e.g. packer:
If you are using lua and the newest
0.8.0 neovim version do:
vim.cmd 'colorscheme oxocarbon-lua'
If you have a vimscript configuration this will get the theme running:
The original theme sets the terminal colors to oxocarbon's pallete, but it seems like a lot of tools use only the few first (black and white), which can make the usage of the terminal really annoying.
You can disable hijacking the terminal colors by setting a global variable
oxocarbon_lua_keep_terminal like so:
vim.g.oxocarbon_lua_keep_terminal = true
let g:oxocarbon_lua_keep_terminal = 1
Some people just don't like them - on terminals they often trim the text.
vim.g.oxocarbon_lua_disable_italic = true
let g:oxocarbon_lua_disable_italic = 1
