🏯 Solarized Osaka

One of the Solarized-inspired dark theme for Neovim written in Lua.

solarized-osaka_screenshot01

🎨 More Colors

Ethan Schoonover originally created the Solarized color scheme in 2011, featuring a set of 16 colors. However, this assortment of colors falls short in providing adequate variations for additional signs, alerts, tooltips, and various other UI components made available by recent Neovim plugins. Furthermore, the text colors in the original theme are somewhat too dark when displayed on modern, vibrant monitors.

Solarized Osaka improves upon this by introducing additional colors, enriching the overall theme to ensure compatibility with newer plugins and enhancing visibility on contemporary monitors. The theme brightens the base colors slightly, creating a visually appealing and functional color palette.

Here is what the improved color palette looks like:

A Figma design is available here.

✨ Features

  • Supports the latest Neovim 0.9.0 features.
  • Enhances terminal colors.
  • Introduces a darker background option for sidebar-like windows.
  • Supports all major plugins.

⚑️ Requirements

πŸ“¦ Installation

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

{
  "craftzdog/solarized-osaka.nvim",
  lazy = false,
  priority = 1000,
  opts = {},
}

πŸš€ Usage

Vim Script

colorscheme solarized-osaka
vim.cmd[[colorscheme solarized-osaka]]

βš™οΈ Configuration

❗️ Set the configuration BEFORE loading the color scheme with colorscheme solarized-osaka.

Solarized Osaka uses the default options, unless setup is explicitly called.

require("solarized-osaka").setup({
  -- your configuration comes here
  -- or leave it empty to use the default settings
  transparent = true, -- Enable this to disable setting the background color
  terminal_colors = true, -- Configure the colors used when opening a `:terminal` in [Neovim](https://github.com/neovim/neovim)
  styles = {
    -- Style to be applied to different syntax groups
    -- Value is any valid attr-list value for `:help nvim_set_hl`
    comments = { italic = true },
    keywords = { italic = true },
    functions = {},
    variables = {},
    -- Background styles. Can be "dark", "transparent" or "normal"
    sidebars = "dark", -- style for sidebars, see below
    floats = "dark", -- style for floating windows
  },
  sidebars = { "qf", "help" }, -- Set a darker background on sidebar-like windows. For example: `["qf", "vista_kind", "terminal", "packer"]`
  day_brightness = 0.3, -- Adjusts the brightness of the colors of the **Day** style. Number between 0 and 1, from dull to vibrant colors
  hide_inactive_statusline = false, -- Enabling this option, will hide inactive statuslines and replace them with a thin border instead. Should work with the standard **StatusLine** and **LuaLine**.
  dim_inactive = false, -- dims inactive windows
  lualine_bold = false, -- When `true`, section headers in the lualine theme will be bold

  --- You can override specific color groups to use other groups or a hex color
  --- function will be called with a ColorScheme table
  ---@param colors ColorScheme
  on_colors = function(colors) end,

  --- You can override specific highlights to use other groups or a hex color
  --- function will be called with a Highlights and ColorScheme table
  ---@param highlights Highlights
  ---@param colors ColorScheme
  on_highlights = function(highlights, colors) end,
})

πŸͺ“ Overriding Colors & Highlight Groups

How the highlight groups are calculated:

  1. colors are determined based on your configuration, with the ability to override them using config.on_colors(colors).
  2. These colors are utilized to generate the highlight groups.
  3. config.on_highlights(highlights, colors) can be used to override highlight groups.

For default values of colors and highlights, please consult the colors.lua file.

Settings and color alteration demonstration

require("solarized-osaka").setup({
  -- disable italic for functions
  styles = {
    functions = {}
  },
  sidebars = { "qf", "vista_kind", "terminal", "packer" },
  -- Change the "hint" color to the "orange" color, and make the "error" color bright red
  on_colors = function(colors)
    colors.hint = colors.orange
    colors.error = "#ff0000"
  end
})
require("solarized-osaka").setup({
  on_highlights = function(hl, c)
    local prompt = "#2d3149"
    hl.TelescopeNormal = {
      bg = c.bg_dark,
      fg = c.fg_dark,
    }
    hl.TelescopeBorder = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
    hl.TelescopePromptNormal = {
      bg = prompt,
    }
    hl.TelescopePromptBorder = {
      bg = prompt,
      fg = prompt,
    }
    hl.TelescopePromptTitle = {
      bg = prompt,
      fg = prompt,
    }
    hl.TelescopePreviewTitle = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
    hl.TelescopeResultsTitle = {
      bg = c.bg_dark,
      fg = c.bg_dark,
    }
  end,
})

Fix undercurls in Tmux

To have undercurls show up and in color, add the following to your Tmux configuration file:

# Undercurl
set -g default-terminal "${TERM}"
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours - needs tmux-3.0

# Alacritty
set -as terminal-features ",alacritty:RGB"
