Neovim version (nvim -v)

v0.10.0

Operating system/version

Void Linux x86_64

Describe the bug

Setting the LineNr guifg highlight has no visual effect. When starting neovim, both the visual appearance of the line number and the value of LineNr guifg is #3b4261:

But after changing the LineNr highlight value the visual appearance of the line numbers remains unchanged:

Steps To Reproduce

1. Open any file with nvim path/to/file
2. Issue the following command :hi LineNr guifg=white

Expected Behavior

Expected the foreground color of the line numbers in the gutter to change to white.

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here
--
vim.o.nu = true
vim.o.rnu = true

Do you mean the [relative] line numbers on the left side?

I also changed them, along with comments, a bit brighter because I prefer using my monitor with lower brightness and night light. As I understand the LineNr only changes the current line number color if cursorLine is not enabled.

Here's the config as code.

{
  'folke/tokyonight.nvim',
  priority = 1000, -- Make sure to load this before all the other start plugins.
  opts = {
    on_colors = function(colors)
      colors.comment = '#6272a4'
    end,
    on_highlights = function(hl, colors)
      local commentColor = colors.comment
      hl.LineNrAbove = {
        fg = commentColor,
      }
      hl.LineNrBelow = {
        fg = commentColor,
      }
      hl.DiagnosticUnnecessary = { fg = commentColor }
    end,
  },
  init = function()
    vim.cmd.colorscheme 'tokyonight-storm'
    vim.cmd.hi 'Comment gui=none'
  end,
},
