Configuration

There is no need to call setup if you are ok with the defaults.

-- Default options:
require('kanagawa').setup({
    compile = false,             -- enable compiling the colorscheme
    undercurl = true,            -- enable undercurls
    commentStyle = { italic = true },
    functionStyle = {},
    keywordStyle = { italic = true},
    statementStyle = { bold = true },
    typeStyle = {},
    transparent = false,         -- do not set background color
    dimInactive = false,         -- dim inactive window `:h hl-NormalNC`
    terminalColors = true,       -- define vim.g.terminal_color_{0,17}
    colors = {                   -- add/modify theme and palette colors
        palette = {},
        theme = { wave = {}, lotus = {}, dragon = {}, all = {} },
    },
    overrides = function(colors) -- add/modify highlights
        return {}
    end,
    theme = "wave",              -- Load "wave" theme when 'background' option is not set
    background = {               -- map the value of 'background' option to a theme
        dark = "wave",           -- try "dragon" !
        light = "lotus"
    },
})

-- setup must be called before loading
vim.cmd("colorscheme kanagawa")

NOTE 1: If you enable compilation, make sure to run this command every time you make changes to your config. NOTE 2: Kanagawa adjusts to the value of some options. Make sure that the options 'laststatus' and 'cmdheight' are set before calling setup.

" 1. Modify your config
" 2. Restart nvim
" 3. Run this command:
:KanagawaCompile

Themes

Kanagawa comes in three variants:

• wave the default heart-warming theme,
• dragon for those late-night sessions
• lotus for when you're out in the open.

Themes can be changed in three ways:

• Setting config.theme to the desired theme. Note that vim.o.background must be unset.
• Using the background option: Any change to the value of vim.o.background will select the theme mapped by config.background. Use vim.o.background = "" to unset this option.
• Loading the colorscheme directly with:

  vim.cmd("colorscheme kanagawa-wave")
  vim.cmd("colorscheme kanagawa-dragon")
  vim.cmd("colorscheme kanagawa-lotus")

  or

  require("kanagawa").load("wave")

Customization

In kanagawa, there are two kinds of colors: PaletteColors and ThemeColors; PaletteColors are defined directly as RGB Hex strings, and have arbitrary names that recall their actual color. Conversely, ThemeColors are named and grouped semantically on the basis of their actual function.

In short, a palette defines all the available colors, while a theme maps the PaletteColors to specific ThemeColors and the same palette color may be assigned to multiple theme colors.

You can change both theme or palette colors using config.colors. All the palette color names can be found here, while their usage by each theme can be found here.

require('kanagawa').setup({
    ...,
    colors = {
        palette = {
            -- change all usages of these colors
            sumiInk0 = "#000000",
            fujiWhite = "#FFFFFF",
        },
        theme = {
            -- change specific usages for a certain theme, or for all of them
            wave = {
                ui = {
                    float = {
                        bg = "none",
                    },
                },
            },
            dragon = {
                syn = {
                    parameter = "yellow",
                },
            }
            all = {
                ui = {
                    bg_gutter = "none"
                }
            }
        }
    },
    ...
})

You can also conveniently add/modify hlgroups using the config.overrides option. Supported keywords are the same for :h nvim_set_hl {val} parameter.

require('kanagawa').setup({
    ...,
    overrides = function(colors)
        return {
            -- Assign a static color to strings
            String = { fg = colors.palette.carpYellow, italic = true },
            -- theme colors will update dynamically when you change theme!
            SomePluginHl = { fg = colors.theme.syn.type, bold = true },
        }
    end,
    ...
})

Common customizations

Remove gutter background

Remove the background of LineNr, {Sign,Fold}Column and friends

colors = {
    theme = {
        all = {
            ui = {
                bg_gutter = "none"
            }
        }
    }
}

Transparent Floating Windows

This will make floating windows look nicer with default borders.

overrides = function(colors)
    local theme = colors.theme
    return {
        NormalFloat = { bg = "none" },
        FloatBorder = { bg = "none" },

        -- Save an hlgroup with dark background and dimmed foreground
        -- so that you can use it where your still want darker windows.
        -- E.g.: autocmd TermOpen * setlocal winhighlight=Normal:NormalDark
        NormalDark = { fg = theme.ui.fg_dim, bg = theme.ui.bg_m3 },

        -- Popular plugins that open floats will link to NormalFloat by default;
        -- set their background accordingly if you wish to keep them dark and borderless
        LazyNormal = { bg = theme.ui.bg_m3, fg = theme.ui.fg_dim },
        MasonNormal = { bg = theme.ui.bg_m3, fg = theme.ui.fg_dim },
    }
end,

If you'd like to keep the floating windows darker, but you're unhappy with how borders are rendered, consider using characters that are drawn at the edges of the box:

{ "🭽", "▔", "🭾", "▕", "🭿", "▁", "🭼", "▏" }

Borderless Telescope

Block-like modern Telescope UI

overrides = function(colors)
    local theme = colors.theme
    return {
        TelescopeTitle = { fg = theme.ui.special, bold = true },
        TelescopePromptNormal = { bg = theme.ui.bg_p1 },
        TelescopePromptBorder = { fg = theme.ui.bg_p1, bg = theme.ui.bg_p1 },
        TelescopeResultsNormal = { fg = theme.ui.fg_dim, bg = theme.ui.bg_m1 },
        TelescopeResultsBorder = { fg = theme.ui.bg_m1, bg = theme.ui.bg_m1 },
        TelescopePreviewNormal = { bg = theme.ui.bg_dim },
        TelescopePreviewBorder = { bg = theme.ui.bg_dim, fg = theme.ui.bg_dim },
    }
end,

Dark completion (popup) menu

More uniform colors for the popup menu.

overrides = function(colors)
    local theme = colors.theme
    return {
        Pmenu = { fg = theme.ui.shade0, bg = theme.ui.bg_p1 },
        PmenuSel = { fg = "NONE", bg = theme.ui.bg_p2 },
        PmenuSbar = { bg = theme.ui.bg_m1 },
        PmenuThumb = { bg = theme.ui.bg_p2 },
    }
end,

Integration

-- Get the colors for the current theme
local colors = require("kanagawa.colors").setup()
local palette_colors = colors.palette
local theme_colors = colors.theme

-- Get the colors for a specific theme
local wave_colors = require("kanagawa.colors").setup({ theme = 'wave' })
