A dark and light Neovim theme written in fennel, inspired by IBM Carbon. This is the reference implementation of the oxocarbon theme.

The color palette expands on Nyoom's unique aesthetic and represents a contemporary and ever-changing IBM. Balancing mankind and machine, the colors are harmonious with nature, yet chosen for their luminous quality in the digital world. The oxocarbon color palette is a subset of the broader IBM palette.

The colorscheme is centered around a vibrant set of blues, combined with an industrial set of grays. The full palette extends from the blue family to the edges of the blue spectrum—even the reds contain a hint of blue.

The resulting palette is a set of colors that portrays a singular IBM. Of the world and digital. Useful and judicious. Having multiple gray families gives each design the opportunity for nuance and meaningful moments of color. Each experience should be dominated by the grays and the core colors of black, white, and the blue family, allowing the other color families to have vibrancy and provide purpose.

Features

Support for popular plugins, such as Lsp, Treesitter, and Semantic Highlighting
Fast and Featureful. Supports all the highlights you'll ever need without making a dent on startuptime
Uses Termguicolors but its compatible with 16-color terminals as well

Plugin support

The colorscheme explicitly adds highlights for the following plugins:

Vim Diagnostics
Vim LSP
Nvim-Treesitter
Telescope
Nvim-Notify
Nvim-Cmp
NvimTree
Neogit
Gitsigns
Hydra

And many others should "just work!" If you have a plugin that needs explicit highlights, feel free to open an issue or PR and I would be happy to add them.

Install

The colorscheme requires the latest stable or nightly neovim (> v0.7.0)

Packer.nvim

use {'nyoom-engineering/oxocarbon.nvim'}

Lazy.nvim

return { 
  "nyoom-engineering/oxocarbon.nvim"
  -- Add in any other configuration; 
  --   event = foo, 
  --   config = bar
  --   end,
},

Usage

For neovim nightly users:

vim.opt.background = "dark" -- set this to dark or light
vim.cmd.colorscheme "oxocarbon"

For neovim stable users:

vim.opt.background = "dark" -- set this to dark or light
vim.cmd("colorscheme oxocarbon")

For nyoom.nvim users: Nyoom comes bundled with a version of oxocarbon. Enable the ui.nyoom module

Development

You must install hotpot, since is what is used for compiling the fennel code.

HDR Screenshots Look Terrible on Linux

They're all way too low contrast. There's a stream of theprimeagen spending way too long trying to find a good screenshot. (He finally manages to get one here.)

I don't know what the hell you used, but please for the love of your theme, don't disgrace it with these terrible screenshots. For the record, it looks great on my machine (and probably yours too).

This is my config:

use { "shaunsingh/oxocarbon.nvim", run = "./install.sh" }

I install successfully using :PackerSync but enabling the colourscheme displays the following error:

Update colorscheme to better support c++

Before I made my changes, my c++ code wasn't being highlighted very well. Most noticeable were the lack of highlighting on the builtin types and the namespaces. This confused me at first as I thought that treesitter wasn't working.

After adding highlighting to builtin types and namespaces, the highlighting looks something like this:

I hope that this is an improvement that fixes something that just wasn't implemented and doesn't break some other language's highlighting.

Thanks for this amazing theme!

Bug: oxocarbon can only be set as color scheme once
To reproduce:

remove everything that sets a colorscheme from your neovim config

run :colorscheme oxocarbon

run :colorscheme blue (or any other colorscheme)

run :colorscheme oxocarbon again

The first two colorscheme will work, but setting oxocarbon as colorscheme a second time does not work. This is relevant for some use cases where you want to change your colorscheme during runtime, for example styler or auto-dark-mode.

I checked, oxocarbon seems to be the only theme that has this issue, other themes, builtin or from the community, do not have this problem.

Inconsistent colors
I have treesitter with typescript and tsx installed.

When I do this:

vim.cmd.colorscheme "oxocarbon"

I get incorrect colors:

But when I load a different theme first:

vim.cmd.colorscheme "everforest" vim.cmd.colorscheme "oxocarbon"

I get correct colors:

Am I doing something wrong? It might have to do something with #4

Fatal runtime error: Rust panic on nightly neovim

Hey! Great colorscheme.

For some reason, a few days ago it started crashing nightly neovim for me. I'm using the AppImage version.

Error in `oxocarbon.so:1`

Hi, I get this error when trying the theme with :colo oxocarbon.

color isn't applied to all jsx tags

Only applying the colors to custom components (like "Section") and not for normal tags (like "div"): Obs: I don't know if it's a bug report or a feature request. Also, white for props/attributes doesn't seems right.

Abort --> free-ing un-malloc'd memory - when starting on MacOS / iterm2

I'm running nvim version 0.9.0 installed from Brew

After setting the color theme to oxocarbon, neovim crashes with this message:

nvim(64121,0x1047ec580) malloc: *** error for object 0x1046886ae: pointer being freed was not allocated
nvim(64121,0x1047ec580) malloc: *** set a breakpoint in malloc_error_break to debug

I'm assuming that this is due to the new nvim minor version. Just guessing that the native oxocarbon stuff was compiled against 0.8.*.

missing diff & CurSearch highlights

Hello, seems like oxocarbon.nvim does not set up any highlighting groups for diffs. This results in ugly (default) highlights in various plugins like neogit and diffview.

Also, CurSearch highlight is used for highlighting search result under the cursor - at the moment such search result gets no highlight at all. It could be as simple as linking it to IncSearch.

Could you please add those as well?

fix 0.8.0 crashes

closes #22 and other crashes related to neovim 0.8

This was done by bumping the version of nvim-oxi dependency.

To make this backwards compatible and not cause breaking changes to those who already have a working version, the package now incorporates the same features as nvim-oxi. As for the installer, install.sh script was also updated to grab neovim's current minor release and match it with the corresponding feature to compile appropriately.

Light colorscheme LspReferences Highlight

Hi, I just started using oxocarbon, both the dark and light versions and really like it. Thanks for this!

In the light version everything is great, however the LspReferenceText background is quite dark, I think it is base03=#161616. Not sure if this is a choice by design, but it really makes it difficult to see the text behind it many times:

I just want to know if this is a design choice, otherwise I can change it in my own config.

Thanks in advance!
