Question

Hi,

I have a nice color theme generated with color randomhue.
Is there a way to save it for later use?

Yes:

• See the applied background+foreground colors as guibg + guifg fields of :hi Normal.
• Create a '~/.config/nvim/colors/my_beautiful_scheme.lua' file.
• Populate it with contents similar to 'randomhue' color scheme file:

  require('mini.hues').setup({
    -- Replace 'background' and 'foreground' with colors you prefer
    background = '#112233',
    foreground = '#ddeeff',
    n_hues = 8,
    saturation = vim.o.background == 'dark' and 'medium' or 'high',
    accent = 'bg',
  })
  
  vim.g.colors_name = 'my_beautiful_scheme'

This can now be used as :colorscheme my_beautiful_scheme.
