Install with your package manager of choice:
-- Lazy
{
"olimorris/onedarkpro.nvim",
priority = 1000 -- Ensure it loads first
}
-- somewhere in your config:
vim.cmd("colorscheme onedark")
-- Packer
use "olimorris/onedarkpro.nvim"
-- somewhere in your config:
vim.cmd("colorscheme onedark")

The colorscheme comes with some useful commands:
:OnedarkproCache
force generate new cache files for the themes (you won't often need this):OnedarkproClean
removes existing cache files for the themes:OnedarkproColors
output all of the current themes colors to a scratch buffer
The theme comes with the ability to export colors to Alacritty, Kitty, Foot, Wezterm, Rio and Windows Terminal using the following commands:
:OnedarkproExportToAlacritty
:OnedarkproExportToFoot
:OnedarkproExportToKitty
:OnedarkproExportToWezterm
:OnedarkproExportToWindowsTerminal
:OnedarkproExportToRio
The templates for these themes can be found in the extra folder.

Currently, there are four themes in the colorscheme:
onedark
onelight
onedark_vivid
onedark_dark
A theme can be set with:
vim.cmd("colorscheme onedark")
A theme has a palette of 13 core colors alongside many additional ones which are used for menus and git diffs for example. These colors can be found in the themes.
The default colors can be changed by specifying the name of the color and a new hex code:
require("onedarkpro").setup({
colors = {
red = "#FF0000"
}
})
Specifying new colors
New colors may be created which will then be merged into a theme's color palette:
require("onedarkpro").setup({
colors = {
my_new_red = "#f44336",
my_new_green = "require('onedarkpro.helpers').darken('green', 10, 'onedark')"
}
})
Note: See the helpers section to understand how to use the color helpers.
These can then be used for custom highlight groups if desired:
require("onedarkpro").setup({
highlights = {
Error = {
fg = "${my_new_red}",
bg = "${my_new_green}"
},
}
})
Specifying colors by theme or background
It's possible to override default colors within a theme such as the bg
color. This is a common question for those who wish to have a darker background than the default. Of course it would make sense to have different bg
colors for the onedark
and onelight
themes. This can be achieved by specifying the theme name as a table, followed by the color:
require("onedarkpro").setup({
colors = {
onedark = { bg = "#FFFF00" }, -- yellow
onelight = { bg = "#00FF00" }, -- green
}
})
Alternatively, you can specify colors by the theme's background color:
require("onedarkpro").setup({
colors = {
dark = { bg = "#FFFF00" }, -- yellow
light = { bg = "#00FF00" }, -- green
}
})
The editor, syntax, filetype and plugin files use a large array of highlight groups. Some examples of how you can customize or override them:
- Using specific hex colors and styles:
require("onedarkpro").setup({
highlights = {
Comment = { fg = "#FF0000", bg = "#FFFF00", italic = true }
}
})
- Referencing the name of colors:
require("onedarkpro").setup({
highlights = {
Comment = { fg = "${my_new_red}", bg = "${yellow}", italic = true }
}
})
- Linking to other highlight groups:
require("onedarkpro").setup({
highlights = {
Comment = { link = "Substitute" }
}
})
- Extending existing highlight groups:
require("onedarkpro").setup({
highlights = {
Comment = { underline = true, extend = true }
}
})
Note: In the example above, an underline style has been applied to the existing
Comment
highlight group.
You can also create your own highlight groups:
require("onedarkpro").setup({
highlights = {
MyNewHighlightGroup = { fg = "${red}" }
}
})
or, if you'd like to disable certain highlight groups:
require("onedarkpro").setup({
highlights = {
["@lsp.type.comment"] = {}
}
})
Note: This can be useful to prevent LSP servers from applying semantic highlights
As with colors, highlight attributes may be specified by using the theme name or the background color. For example:
require("onedarkpro").setup({
highlights = {
Comment = {
fg = { onedark = "${yellow}", onelight = "${my_new_red}" }
}
}
})
Alternatively, by background color:
require("onedarkpro").setup({
highlights = {
Comment = {
fg = { dark = "${yellow}", light = "${my_new_red}" }
}
}
})
Neovim supports the application of highlights to specific buffers via namespaces. To apply highlight groups to a specific namespace, use the ns_id
key:
require("onedarkpro").setup({
highlights = {
Comment = { ns_id = 1, fg = "${light_gray}" }
}
})
Note: For a list of available styles, please refer to the Neovim documentation
Styles can be applied to highlight groups:
require("onedarkpro").setup({
highlights = {
Comment = { italic = true },
Directory = { bold = true },
ErrorMsg = { italic = true, bold = true }
}
})
Within the theme, collections of highlight groups have been grouped together into styles
. For users who use monospaced fonts with nice italics, this can go someway to enhancing the aesthetic of a theme with minimal effort. These styles may be configured as shown in the example below:
require("onedarkpro").setup({
styles = {
types = "NONE",
methods = "NONE",
numbers = "NONE",
strings = "NONE",
comments = "italic",
keywords = "bold,italic",
constants = "NONE",
functions = "italic",
operators = "NONE",
variables = "NONE",
parameters = "NONE",
conditionals = "italic",
virtual_text = "NONE",
}
})
Note: Please see the Contributing guide if you would like add support for new filetypes.
The theme supports opinionated highlighting for filetypes, just like the original Visual Studio Code theme. By default, all of the filetypes supported are loaded at runtime. The theme currently has support for:
comment
go
html
java
javascript
json
lua
markdown
php
python
ruby
rust
scss
toml
typescript
typescriptreact
vue
xml
yaml
Specific filetypes can be disabled as follows:
require("onedarkpro").setup({
filetypes = {
markdown = false,
ruby = false,
}
})
Alternatively, all of the filetypes can be disabled:
require("onedarkpro").setup({
filetypes = {
all = false
}
})
Or, all of the filetypes can be disabled with a select few enabled:
require("onedarkpro").setup({
filetypes = {
all = false,
markdown = true,
ruby = true,
}
})
Adding or modifying filetype highlights
It's likely that you'll wish to add additional filetype highlights or even change the defaults. This can be achieved by adding them as custom highlight groups in the theme:
require("onedarkpro").setup({
highlights = {
["@field.yaml"] = { fg = "${blue}", italic = true }
}
})
In the example above, we have set the field
treesitter highlight group to be blue, but only when the filetype is yaml
. More information can be found via :h treesitter-highlight-groups
.
To determine which highlight group is being applied in Neovim, see the FAQ section.
Note: Semantic tokens are only available in Neovim 0.9+ and with selected LSP servers.
In Neovim, some LSP servers may send tokens to the editor to allow for more intelligent highlighting such as variable scope; a feature which is impossible with Treesitter alone.
Semantic highlighting in Neovim sees highlight groups set which have a priority greater than those of Treesitter and the base vim highlight groups (see :h lsp-semantic_tokens
for more information). A full list of available semantic tokens can be found here.
The colorscheme has defined some semantic tokens (to match the Visual Studio Code theme as closely as possible) and applies them as part of the filetype highlighting. To determine what tokens are available to set or override, use the :Inspect
command.
Finally, the colorscheme has defined some non-filetype tokens as a plugin, named lsp_semantic_tokens
. See the section below for how to disable this.
Note: Please see the Contributing guide if you would like add support for new plugins.
By default, all of the plugins supported by the theme are loaded at runtime. Specific plugins can be disabled as follows:
require("onedarkpro").setup({
plugins = {
nvim_lsp = false,
polygot = false,
treesitter = false
}
})
Alternatively, all of the plugins can be disabled:
require("onedarkpro").setup({
plugins = {
all = false
}
})
Or, all of the plugins can be disabled with a select few enabled:
require("onedarkpro").setup({
plugins = {
all = false,
nvim_lsp = true,
treesitter = true
}
})
Cursorline
Cursorline highlighting is supported in the theme using a cursorline
color (which may of course be overridden). This can be enabled with the following:
require("onedarkpro").setup({
colors = {
cursorline = "#FF0000" -- This is optional. The default cursorline color is based on the background
},
options = {
cursorline = true
}
})
Transparency
The theme supports transparent backgrounds:
require("onedarkpro").setup({
options = {
transparency = true
}
})
By setting the transparency option to true, the Normal
, Folded
, SignColumn
, Statusline
and Tabline
groups will have NONE
as the background color. Additional transparency may be achieved by overriding more highlight groups.
Terminal Colors
By default, the colorscheme changes the colors for Neovim's :terminal
to the current theme. This can be turned off if required.
require("onedarkpro").setup({
options = {
terminal_colors = false
}
})
Highlighting Inactive Windows
The theme supports changing the color of the main window in Neovim when the focus is lost. For example, when a telescope
or packer
pop up appears:
require("onedarkpro").setup({
options = {
highlight_inactive_windows = true
}
})
The theme comes with a set of helpers which enable you to interact with and modify colors. The helper file can be accessed via require("onedarkpro.helpers")
.
Using colors from a theme
It can be useful to access a theme's colors for use within other plugins (such as your statusline) after its loaded. For this, the get_colors
helper can be used:
local color = require("onedarkpro.helpers")
local colors = color.get_colors()
print(colors.purple) -- #c678dd (if using the Onedark theme)
Without specifying a theme name, the helper will get the colors for the currently loaded theme. Alternatively, specify a theme name, such as get_colors("onelight")
.
You can also use the command :OnedarkproColors
to open a scratch buffer with the colors from the currently loaded theme. This then allows a colorizer plugin to highlight the colors.
Note: Please ensure that the colorscheme loads ahead of any plugins which may wish to use the theme's colors.
Using colors before a theme loads
Whilst the get_colors
method is useful in most cases, it may be necessary to get a theme's colors before it has fully loaded. The common use case is for creating custom colors which are based on the theme's own palette and incorporating pback into the theme. For this the get_preloaded_colors
method can be used:
local color = require("onedarkpro.helpers")
local colors = color.get_preloaded_colors()
print(colors.purple) -- #c678dd (if using the Onedark theme)
Note: This will only output the theme's core color palette and not any generated colors.
Darken/Lighten/Brighten colors
The theme also contain helpers darken
, lighten
and brighten
, to allow you to modify custom colors or the theme's own. All three helpers follow the same format and take three parameters:
- color (string) - The name of the color to load (if specifying a theme) or a hex value
- amount (number) - The amount to darken/lighten/brighten the color by (range from -100 to 100)
- theme (string) (optional) - The name of the theme to load a color from
To use this in practice:
local color = require("onedarkpro.helpers")
-- Load the red color from the onedark theme and lighten it by an amount of 7
print(color.lighten("red", 7, "onedark")) -- #e68991
Alternatively:
local color = require("onedarkpro.helpers")
-- Darken Red1 by an amount of 10
print(color.darken("#FF0000", 10)) -- #cc0000
Of course, you're likely to wish to modify colors before the colorscheme loads. There are a number of ways to accomplish this and the most efficient is to pass a function (as a string) to the colors
table in the theme's configuration:
require("onedarkpro").setup({
colors = {
dark_red = "require('onedarkpro.helpers').darken('red', 10, 'onedark')",
},
highlights = {
CustomRedHighlight = {
fg = "${dark_red}",
},
}
})
This prevents the theme from trying to resolve the color before the whole of the configuration has been parsed. This also ensures that the startup time for the theme remains small too.

Javascript/React
Lualine
The theme has Lualine support out of the box for all of its themes. This can be found in the Lualine folder.
Toggling between themes
To enable the easy switching between dark and light colorschemes, the following helper function could be used:
function ToggleTheme()
if vim.o.background == "dark" then
vim.cmd("colorscheme onelight")
else
vim.cmd("colorscheme onedark")
end
end
I want to change a highlight group but I don't know what it is. How do I find out?
If you're using Neovim 0.9+, the :Inspect
command is available.
If you're on an earlier version of Neovim and are using Treesitter, install Playground as this gives you access to the powerful :TSHighlightCapturesUnderCursor
command. This shows any Treesitter or syntax highlight groups under the cursor.
I think the theme would look better if we changed the highlight group of X. Would you accept a PR?
As mentioned at the top of this readme, the theme is based on the One Dark Pro theme for Visual Studio Code. Where possible, I will always reconcile back to that. Unless something looks terrible or the readability can be signficantly improved, I'll nearly always default what the original theme has done. Remember that you can apply your own modifications by configuring highlight groups in your own configuration.
Ok then, but I've noticed some differences between the theme and Visual Studio Code. Why is this?
I've tried to ensure that the theme resembles the original Visual Studio Code theme as much as possible. To that end we have carefully applied custom Treesitter queries to certain filetypes as well as mapped LSP semantic token colors. If you notice any differences, please raise a discussion with supporting screenshots.
