neovim

Generate colour schemes for Neovim.

Description​

Neovim is a hyperextensible Vim-based text editor. The plugin generates a Lua colour scheme file that can be used directly with Neovim's built-in colour scheme system.

Output paths​

~/.config/nvim/colors/tinct.lua
~/.config/nvim/lua/lualine/themes/tinct.lua

Usage​

tinct generate -i image -p ~/wallpaper.jpg -o neovim

With custom theme name​

tinct generate -i image -p ~/wallpaper.jpg -o neovim --neovim.theme-name=my-theme

This generates ~/.config/nvim/colors/my-theme.lua.

Flags​

FlagDefaultDescription
--neovim.output-dir~/.config/nvim/colorsOutput directory for colour scheme
--neovim.theme-nametinctTheme name (used in filename)

Configuration​

After generation, activate the theme in Neovim.

init.lua​

vim.cmd('colorscheme tinct')

init.vim​

colorscheme tinct

Auto-reload​

The generated colour scheme includes a file system watcher that automatically reloads colours when tinct updates the theme. This provides live theme updates without restarting Neovim.

Themed elements​

The colour scheme affects:

  • Editor background and foreground
  • Syntax highlighting groups
  • Line numbers and sign column
  • Status line
  • Popup menus
  • Diff highlighting
  • Search highlighting
  • Visual selection
  • Error and warning messages

Lualine​

Tinct generates a standalone lualine.nvim theme file alongside the main colourscheme.

Automatic theming (no configuration needed)​

If you use lualine with its default theme = 'auto' setting, lualine will automatically extract colours from tinct's highlight groups (Normal, String, Number, Special, Identifier, PmenuSel, StatusLine). No extra configuration is required.

Explicit theme​

To use the dedicated tinct lualine theme, set it in your lualine configuration:

require('lualine').setup({
  options = {
    theme = 'tinct',
  },
})

The generated theme file at ~/.config/nvim/lua/lualine/themes/tinct.lua provides colour definitions for all lualine modes (normal, insert, visual, replace, command, inactive) using the same palette as the main colourscheme.

If you use a custom --neovim.theme-name, use that name instead:

require('lualine').setup({
  options = {
    theme = 'my-theme',
  },
})

Generated format​

-- Neovim colorscheme generated by tinct

vim.cmd('hi clear')
if vim.fn.exists('syntax_on') then
    vim.cmd('syntax reset')
end

vim.o.background = 'dark'
vim.g.colors_name = 'tinct'

-- Highlight groups
local highlights = {
    Normal = { fg = '#cdd6f4', bg = '#1e1e2e' },
    Comment = { fg = '#6c7086', italic = true },
    String = { fg = '#a6e3a1' },
    Function = { fg = '#89b4fa' },
    Keyword = { fg = '#f5c2e7' },
    -- ... additional groups
}

for group, opts in pairs(highlights) do
    vim.api.nvim_set_hl(0, group, opts)
end
