If you are using a terminal colorsceme based on Wombat and would like your colors to match more percisely, you can define a new set of ansi colors in a lua file similar to the one shown in `lua/wombat/ansi_iterm.lua'. It should be in a path `lua/wombat/ansi_new_theme.lua`.
Then you can create a new colorscheme file similar to `colors/wombat.vim`, but reference the new file name instead of `ansi_iterm`.
This will define a new colorscheme using the same mappings as defined in wombat.nvim, but with your new ansi colors.
