A muted, elegant dark color theme with warm undertones and a soft lavender identity. 
 Built for Neovim, VS Code, terminals, tmux, and CLI tools.

- **WCAG AA contrast** — validated at build time, never ships unreadable text
- **15 Neovim plugin integrations** — Telescope, cmp, gitsigns, mini.nvim, noice, trouble, flash, snacks, and more
- **Treesitter + LSP semantic tokens** — full highlighting with 450+ groups
- **13 terminal/CLI targets** — Kitty, Alacritty, WezTerm, Ghostty, iTerm2, foot, Windows Terminal, tmux, fzf, bat, delta, lazygit, OpenCode

## Installation

### Neovim

#### lazy.nvim

```lua
{
  "danfry1/lume",
  lazy = false,
  priority = 1000,
  config = function()
    require("lume").setup()
    vim.cmd("colorscheme lume")
  end,
}
```

<details>
<summary>packer.nvim</summary>

```lua
use {
  "danfry1/lume",
  config = function()
    require("lume").setup()
    vim.cmd("colorscheme lume")
  end,
}
```

</details>

#### Options

All options are optional — defaults work out of the box.

```lua
require("lume").setup({
  transparent = false, -- set to true to use your terminal's background
  italics = true,      -- set to false to disable italic comments/keywords
  palette_overrides = { -- override base palette colors before they cascade to all groups
    foregrounds = { text = "#c8c8d8" },   -- softer foreground
    accents = { lavender = "#a890d0" },   -- tweak any accent
  },
  custom_highlights = function(colors, variant)
    -- colors contains: backgrounds, foregrounds, accents, ansi, special
    -- variant is "dark" (or "light" when a light theme is added)
    return {
      Normal = { bg = "#1E1F2E" },
      MiniDiffSignAdd = { fg = colors.accents.sage },
    }
  end,
})
```

`palette_overrides` accepts a table or a function. When a function, it receives the full palette and variant, and should return a table of overrides:

```lua
palette_overrides = function(colors, variant)
  return {
    foregrounds = { text = "#c8c8d8", subtext = "#a0a0b0" },
  }
end,
```

Palette overrides are applied first — all built-in highlight groups and `custom_highlights` will see the modified palette.

#### Plugin support

Highlight groups are included for these plugins (loaded automatically, no config needed):

## Contributing

`palette.json` is the single source of truth for all colors. All theme files are generated from it.

```bash
bun install          # install dependencies
bun run generate     # regenerate all outputs from palette.json
bun test             # run tests
bun run validate     # check WCAG AA contrast ratios
bun run check        # verify generated files are up to date
bun run typecheck    # typecheck TypeScript
```

Please run `bun run generate` and commit the results before opening a PR.
