Did you check the docs?

• [X] I have read all the tokyonight.nvim docs

Is your feature request related to a problem? Please describe.

Thank you for the wonderful plugin.

I am using glyph_palette.vim, but I am encountering the following error.

   Error  09:01:33 notify.error lazy.nvim Failed to source `~/.local/share/nvim/lazy/glyph-palette.vim/plugin/glyph_palette.vim`

vim/_editor.lua:0: VimEnter Autocommands for "*"..script nvim_exec2() called at VimEnter Autocommands for "*":0..~/.local/share/nvim/lazy/glyph-palette.vim/plugin/glyph_palette.vim[7]..function glyph_palette#defaults#highlight[4]..<lambda>2, line 1: Vim(call):E121: undefined variables: g:terminal_color_13

Describe the solution you'd like

https://github.com/folke/tokyonight.nvim/blob/817bb6ffff1b9ce72cdd45d9fcfa8c9cd1ad3839/lua/tokyonight/theme.lua#L55-L56

Could you add the color for vim.g.terminal_color_13 here?

Describe alternatives you've considered

I considered setting it manually.

vim.cmd([[
    let g:terminal_color_13 = '#000'
    colorscheme tokyonight-moon
]])

Additional context

If it's an issue with vim-glyph-palette rather than tokyonight.nvim, I'll move it there.

[ksaito422]

The color schemes where the issue occurred are tokyonight-moon and tokyonight-storm.

I think this is a typo, 18 should actually be 13. There are only 0 - 15 terminal colors.

Thanks.
