🎨 JB for Neovim

Color scheme for Neovim, inspired by JetBrains IDEs.

Dark	Light

Features

• Supports both light and dark themes, with a colorblind-friendly palette for light mode
• Terminal colors
• Lualine theme included
• Lualine component for a Navigation Bar similar to JetBrains IDEs but only for dir path part
• Generates ProjectColor highlight group based on the path
• Generates highlights for icons JBIcon<Kind>
• Provides a table with icons visually similar to JB's ones

Installation

Install the theme with your preferred package manager, such as folke/lazy.nvim:

return {
    "nickkadutskyi/jb.nvim",
    lazy = false,
    priority = 1000,
    opts = {},
    config = function()
        -- require("jb").setup({transparent = true})
        vim.cmd("colorscheme jb")
    end,
}

Plugin Notes

hrsh7th/nvim-cmp

If you use custom view for entries (opts>view>entries>name) cmp creates a custom window instead of native built-in popup. To improve the view you can link highlight groups like this:

window = {
    completion = cmp.config.window.bordered({
        winhighlight = "Normal:Pmenu,FloatBorder:DialogFloatBorder,CursorLine:PmenuSel,Search:None",
    }),
    documentation = cmp.config.window.bordered({
        winhighlight = "Normal:Pmenu,FloatBorder:DialogFloatBorder,CursorLine:PmenuSel,Search:None",
    }),
},

You can have any config just make sure Normal:Pmenu and CursorLine:PmenuSel is present in winhighlight.

Usage

vim.cmd("colorscheme jb")

colorscheme jb

Change light/dark theme:

vim.o.background = "light"

set background=light

Configuration

---@class jb.Config
M.defaults = {
    -- Disable bold or italic for all highlights
    disable_hl_args = {
        bold = false,
        italic = false,
    },
    -- Control snacks.nvim related styles
    snacks = {
        explorer = {
            -- Enable folke/snacks.nvim styling for explorer
            enabled = true,
        },
    },
    telescope = {
        -- Enable telescope.nvim styling
        enabled = true,
    },
    -- Type: jb.DisabledPlugin[]
    -- Disable plugin highlight sets by plugin id, e.g. "nvim-telescope/telescope.nvim"
    disabled_plugins = {},
    -- Enable this to remove background from Normal and NormalNC
    transparent = false,
    -- Enable colorblind-friendly palette (light mode only)
    -- Replaces green/purple/teal tokens with blue and near-black alternatives
    colorblind = false,
    integrations = {
        -- Match Ghostty's background to the statusbar while Neovim is open
        ghostty = false,
    },
}

Overriding Colors & Highlight Groups

Extras

Extra color configs for Kitty, Alacritty, Ghostty can be found in extras. To use them, refer to their respective documentation.

Set integrations.ghostty = true before loading the colorscheme to temporarily match Ghostty's background to the JB statusbar. Ghostty's configured background is restored when Neovim exits.

Development

IntelliJ color snapshots come from the private plugin in tools/intellij-palette-exporter. That generated file is stored in lua/jb/intellij-palette.json; Neovim highlight mappings are stored separately in lua/jb/highlights.json.

When changing either palette file, regenerate the compiled palette used at runtime:

nvim --headless -u NONE --noplugin \
  +'set runtimepath^=/absolute/path/to/jb.nvim' \
  +'lua dofile("/absolute/path/to/jb.nvim/scripts/generate_palette_compiled.lua")' \
  +qa
