Zenbones

Zenbones is a collection of vim/neovim colorschemes designed to highlight code using contrasts and font variations. Colors are tasked only for other roles such as diagnostics, diffs, search matches.

Usage

Just apply the colorscheme as usual:

set termguicolors

colorscheme zenbones " light
colorscheme zenflesh " dark

colorscheme zenwritten   " Zero hue and saturation version
colorscheme neobones     " https://neovim.io flavor
colorscheme vimbones     " https://www.vim.org flavor
colorscheme rosebones    " Rosé Pine flavor - https://rosepinetheme.com
colorscheme forestbones  " Everforest flavor - https://github.com/sainnhe/everforest
colorscheme nordbones    " Nord flavor - https://www.nordtheme.com/docs/colors-and-palettes
colorscheme tokyobones   " Tokyo Night flavor - https://github.com/enkia/tokyo-night-vscode-theme#color-palette

It works pretty much the same as the first one but pretty handy when extending or customizing the colors to your likings.

Configuration

Configuration is only available for neovim. There are two ways to set configuration. First:

" vimscript
let g:zenbones_solid_line_nr = v:true
let g:zenbones_darken_comments = 45

-- lua
vim.g.zenbones_solid_line_nr = true
vim.g.zenbones_darken_comments = 45

Second way is to set configuration is to assign a dictionary to the prefix:

" vimscript
let g:forestbones = #{ solid_line_nr: v:true, darken_comments: 45 }

-- lua
vim.g.forestbones = { solid_line_nr = true, darken_comments = 45 }

Notes: Flavors accept their own configuration by replacing the prefix with the flavor name e.g. g:rosebones_italic_comments.

Option	Background	Default	Description
lightness	light	nil	Change background colors lightness. Options: 'bright', 'dim'.

g:zenbones_compat

Set to 1 to enable compatibility mode. Enable in vim.

lightline

let g:lightline = #{ colorscheme: 'zenbones' } " or zenflesh

lualine

require("lualine").setup {
	options = { theme = "zenbones" }, -- or zenflesh
}

Advanced Usage

Zenbones is pretty extensible thanks to Lush. You can easily retrieve the colors in lua:

local theme = require "zenbones" -- or zenflesh
local palette = require "zenbones.palette"

print(theme.StatusLine.bg.hex)
print(palette.blossom.darken(20).hex)

Here's an example of how to extend/override some highlights.

lua/customize_zenbones.lua:

local lush = require "lush"
local base = require "zenbones"

-- Create some specs
local specs = lush.parse(function()
	return {
		TabLine { base.TabLine, gui = "italic" }, -- setting gui to "italic"
	}
end)
-- Apply specs using lush tool-chain
lush.apply(lush.compile(specs))

And then somewhere in your init.vim:

autocmd ColorScheme zenbones lua require "customize_zenbones"
colorscheme zenbones

See also Lush's documentation for more options.

Create your own colorscheme

You can ultimately create your own colorscheme that is based on zenbones by defining a palette and generating a specs. Best way to demonstrate this is through an example. Let's make a zenbones-flavored Gruvbox colorscheme called gruvbones.

Let's define our colorscheme in colors/gruvbones.lua. It contains the following:

local colors_name = "gruvbones"
vim.g.colors_name = colors_name -- Required when defining a colorscheme

local lush = require "lush"
local hsluv = lush.hsluv -- Human-friendly hsl
local util = require "zenbones.util"

local bg = vim.opt.background:get()

-- Define a palette. Use `palette_extend` to fill unspecified colors
-- Based on https://github.com/gruvbox-community/gruvbox#palette
local palette
if bg == "light" then
	palette = util.palette_extend({
		bg = hsluv "#fbf1c7",
		fg = hsluv "#3c3836",
		rose = hsluv "#9d0006",
		leaf = hsluv "#79740e",
		wood = hsluv "#b57614",
		water = hsluv "#076678",
		blossom = hsluv "#8f3f71",
		sky = hsluv "#427b58",
	}, bg)
else
	palette = util.palette_extend({
		bg = hsluv "#282828",
		fg = hsluv "#ebdbb2",
		rose = hsluv "#fb4934",
		leaf = hsluv "#b8bb26",
		wood = hsluv "#fabd2f",
		water = hsluv "#83a598",
		blossom = hsluv "#d3869b",
		sky = hsluv "#83c07c",
	}, bg)
end

-- Generate the lush specs using the generator util
local generator = require "zenbones.specs"
local base_specs = generator.generate(palette, bg, generator.get_global_config(colors_name, bg))

-- Optionally extend specs using Lush
local specs = lush.extends({ base_specs }).with(function()
	return {
		Statement { base_specs.Statement, fg = palette.rose },
		Special { fg = palette.water },
		Type { fg = palette.sky, gui = "italic" },
	}
end)

-- Pass the specs to lush to apply
lush(specs)

-- Optionally set term colors
require("zenbones.term").apply_colors(palette)

And there you have it. Just call colorscheme gruvbones to use your new colorscheme. It respects &background and other configurations too.

Also checkout the neobones and rosebones colorscheme for a similar and complete example.
