rainbow vim plugin does not work with neovim(0.5.1) on NixOS (nixpkgs-unstable), out of the box

Describe the bug

I added rainbow to the list of neovim plugins I use, YouCompleteMe , works. I do not see a difference in the syntax color with rainbow vim plugin.

To Reproduce

In /etc/nixos/configuration.nix include the following block of code

    #NeoVim#
    programs.neovim = {
      enable = true;
      defaultEditor = true;
      viAlias = true;
      configure = {
        customRC = ''
          set undofile
        '';
      packages.myVimPackage = with pkgs.vimPlugins; {
      start = [ YouCompleteMe rainbow ];
      };

      };

    };
    #End NeoVim#

It already works, you can try :RainbowToggle to confirm that.

And if you want it activated by default, add following to your customRC

programs.neovim = {
  configure = {
    customRC = ''
      let g:rainbow_active = 1
    '';
  };
};

@luochen1990 , thanks for the help, I was running the wrong vim command to change the color scheme in vim.
