I’m trying to change the background of the neovim using lua.

-- init.lua

vim.o.termguicolors = true

vim.api.nvim_set_hl(0, "Normal", { bg="#04110d" })

The expected result should be like this (modified directly via Terminal settings)

But it renders like this

I use the default Ubuntu Terminal with default configuration.

I tried to use a “simplier” color and it works

Instead of this

vim.api.nvim_set_hl(0, "Normal", { bg="#04110d" })

I used this

vim.api.nvim_set_hl(0, "Normal", { bg="#ff0000" })

(sorry for the red image)

Does anyone know the root cause of the problem and how I can fix that?

I’d expect the specified color #04110d to work as expected (displaying the dark green background).

Thanks
