Features

• Create colorscheme object (see :h MiniColors-colorscheme): either manually (:h MiniColors.as_colorscheme()) or by querying present color schemes (including currently active one; see :h MiniColors.get_colorscheme()).

• Infer data about color scheme and/or modify based on it:

  • Add transparency by removing background color (requires transparency in terminal emulator).
  • Infer cterm attributes based on gui colors making it compatible with 'notermguicolors'.
  • Resolve highlight group links.
  • Compress by removing redundant highlight groups.
  • Extract palette of used colors and/or infer terminal colors based on it.

• Modify colors to better fit your taste and/or goals:

  • Apply any function to color hex string.
  • Update channels (like lightness, saturation, hue, temperature, red, green, blue, etc.). Use either own function or one of the implemented methods:
    • Add value to channel or multiply it by coefficient. Like "add 10 to saturation of every color" or "multiply saturation by 2" to make colors more saturated (less gray).
    • Invert. Like "invert lightness" to convert between dark/light theme.
    • Set to one or more values (picks closest to current one). Like "set to one or two hues" to make mono- or dichromatic color scheme.
    • Repel from certain source(s) with stronger effect for closer values. Like "repel from hue 30" to remove red color from color scheme. Repel hue (how much is removed) is configurable.
  • Simulate color vision deficiency.

• Once color scheme is ready, either apply it to see effects right away or write it into a Lua file as a fully functioning separate color scheme.

• Experiment interactively with a feedback.

• Animate transition between color schemes either with MiniColors.animate() or with :Colorscheme user command.

• Convert within supported color spaces (MiniColors.convert()):

  • Hex string.
  • 8-bit number (terminal colors).
  • RGB.
  • Oklab, Oklch, Okhsl (https://bottosson.github.io/posts/oklab/).

Tweak quick start

• Execute :lua require('mini.colors').interactive().
• Experiment by writing calls to exposed color scheme methods and applying them with <M-a>. For more information, see :h MiniColors-colorscheme-methods and :h MiniColors-recipes.
• If you are happy with result, write color scheme with <M-w>. If not, reset to initial color scheme with <M-r>.
• If only some highlight groups can be made better, adjust them manually inside written color scheme file.

Installation

This plugin can be installed as part of 'mini.nvim' library (recommended) or as a standalone Git repository.

There are two branches to install from:

• main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
• stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

• 'mini.nvim' library:

  Branch	Code snippet
  Main	Follow recommended 'mini.deps' installation
  Stable	Follow recommended 'mini.deps' installation

• Standalone plugin:

  Branch	Code snippet
  Main	add('nvim-mini/mini.colors')
  Stable	add({ source = 'nvim-mini/mini.colors', checkout = 'stable' })

• 'mini.nvim' library:

  Branch	Code snippet
  Main	{ 'nvim-mini/mini.nvim', version = false },
  Stable	{ 'nvim-mini/mini.nvim', version = '*' },

• Standalone plugin:

  Branch	Code snippet
  Main	{ 'nvim-mini/mini.colors', version = false },
  Stable	{ 'nvim-mini/mini.colors', version = '*' },

• 'mini.nvim' library:

  Branch	Code snippet
  Main	Plug 'nvim-mini/mini.nvim'
  Stable	Plug 'nvim-mini/mini.nvim', { 'branch': 'stable' }

• Standalone plugin:

  Branch	Code snippet
  Main	Plug 'nvim-mini/mini.colors'
  Stable	Plug 'nvim-mini/mini.colors', { 'branch': 'stable' }

Important: no need to call require('mini.colors').setup(), but it can be done to improve usability.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

• Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
• Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
