This theme was inspired from my incessant desire to feel like I'm in space when I stare at a computer. "Spaceduck" takes its name from my love of duck dodgers as a kid.

If it looks ugly it's because I don't know what I'm doing pls help. If it's the sexiest thing you've ever seen, well then uhm.. you're welcome

NOTE: This repo hosts the Vim/Neovim spaceduck theme, to install other ports look for the other ports below.

If using Vim/Neovim I recommend installing the vim-polyglot plugin for improved syntax highlighting:

Plug 'sheerun/vim-polyglot'

Vim and Neovim

This repo hosts the Vim/Neovim color scheme.

Install the plugin with whatever plugin manager you use:

Plug 'pineapplegiant/spaceduck', { 'branch': 'main' }

And add this to your vimrc/init.vim configuration file:

    if exists('+termguicolors')
      let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
      let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"
      set termguicolors

   colorscheme spaceduck

Or manually add the color theme to your 'runtimepath' for the file.

:h colors

  let g:airline_theme = 'spaceduck'
lightline normal mode screenshot lightline insert mode screenshot lightline visual mode screenshot lightline replace mode screenshot
    let g:lightline = {
          \ 'colorscheme': 'spaceduck',
          \ }

Don't be afraid of the vim documentation either for more information, like for manual installs! :h colorscheme

lualine normal mode screenshot lualine insert mode screenshot lualine visual mode screenshot lualine replace mode screenshot

You only really need 'theme': 'spaceduck', but this is what I have in my vimrc:

  let g:lualine = {
      \'options' : {
      \  'theme' : 'spaceduck',
      \  'section_separators' : ['', ''],
      \  'component_separators' : ['', ''],
      \  'icons_enabled' : v:true,
      \'sections' : {
      \  'lualine_a' : [ ['mode', {'upper': v:true,},], ],
      \  'lualine_b' : [ ['branch', {'icon': '',}, ], ],
      \  'lualine_c' : [ ['filename', {'file_status': v:true,},], ],
      \  'lualine_x' : [ 'encoding', 'fileformat', 'filetype' ],
      \  'lualine_y' : [ 'progress' ],
      \  'lualine_z' : [ 'location'  ],
      \'inactive_sections' : {
      \  'lualine_a' : [  ],
      \  'lualine_b' : [  ],
      \  'lualine_c' : [ 'filename' ],
      \  'lualine_x' : [ 'location' ],
      \  'lualine_y' : [  ],
      \  'lualine_z' : [  ],
      \'extensions' : [ 'fzf' ],

  lua require("lualine").setup()

Other Spaceduck Ports


Terminal install can be found at this repo:


Vscode theme can be found at this repo:


Emacs theme can be found at this repo:


  • Go to User Menu > Preferences > Sidebar Theme
  • In the bottom of the window, look for a "customize your theme and share it with others" link
  • Copy and paste the values below:
    • #0f111b,#7A5CCC,#7A5CCC,#ffffff,#16172D,#ecf0c1,#5CCC96,#00A3CC,#0f111b,#ecf0c1


Checkout some tmux config inspiration here at the terminal repo. Or if you're in a rush you can use this basic one:

  # Basic color support setting
  set-option -g default-terminal "screen-256color"

  # Default bar color
  set-option -g status-style bg='#1b1c36',fg='#ecf0c1'

  # Active Pane
  set -g pane-active-border-style "fg=#5ccc96"

  # Inactive Pane
  set -g pane-border-style "fg=#686f9a"

  # Active window
  set-option -g window-status-current-style bg='#686f9a',fg='#ffffff'

  # Message
  set-option -g message-style bg='#686f9a',fg='#ecf0c1'
  set-option -g message-command-style bg='#686f9a',fg='#ecf0c1'

  # When Commands are run
  set -g message-style "fg=#0f111b,bg=#686f9a"


True color

Make sure you are using a terminal emulator that supports truecolor.

Read more about truecolor support here.

Colors don't look right

If you are running vim within tmux, you may run into some truecolor issues.

To fix, add this to you tmux.conf:

    set -g terminal-overrides ',xterm-256color:Tc'
    set -g default-terminal "tmux-256color"
    set -as terminal-overrides ',xterm*:sitm=\E[3m'

And in your .bash_profile or .zshrc:

  export TERM="xterm-256color"

If you'd like to contribute please reach out! I don't know what I'm doing. Try to send a screenshot when posting issues as well. If you port it to whatever you're using, send me a link so I can link it here!

Vim Estilo

I currently use estilo to manage colors for Vim/Neovim, please install the dependencies to compile the colors specified in the YAML into the color scheme.

To find the current syntax element under the cursor, I use this mapping which maps Ctrl+a to find the id under the cursor:

" Show syntax color highlighting groups for word under cursor
    nmap <c-a> :call <SID>SynStack()<CR>
    function! <SID>SynStack()
      if !exists("*synstack")
      echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')

This will show you the syntax ID to where we can then modify the color of that word.

Testing colors look good

  • To test that colors look good, you can run: :source $VIMRUNTIME/syntax/hitest.vim this will open a buffer of all color groups defined!
  • Check current defined colors in buffer :highlight or :hi for short.
  • Looking for more syntax elements? Check out $VIMRUNTIME/syntax/ for all of vim's language support.
