Having Issues With Using 'hallo.el' Example Theme, And Creating A Custom Theme

["Samuel Banya" <sbanya@fastmail.com>]

Hey there,
I've been following along with this video:
Emacs Tips - How to Create Your Own Color Theme (https://www.youtube.com/watch?v=kCCIudu53Zg)

This video basically uses this theme as an example with the 'autothemer' MELPA package:
https://github.com/daviwil/emacs-from-scratch/blob/master/hallo-theme.el

The problem I have is, I can't get even the example 'hallo' theme to load with 'M-x load-theme hallo'.

More so, I've been trying to create my own Morrowind theme here:
https://github.com/SamuelBanya/emacs-morrowind-theme

Both themes just won't work.

I have a literate config, so here's config on GitHub with 'configuration.org' and 'init.el' present:
https://github.com/SamuelBanya/SamsEmacs 

Here's the current output of ~/.emacs.d on my machine (NOTE: The symlinks are because I use GNU Stow to stow away dotfiles like this with 'stow -t ~/.emacs.d'):
  /home/sam/.emacs.d:

Here's the debugger output when I attempted to load the theme:
Debugger entered--Lisp error: (error "Unable to find theme file for ‘emacs-morrowind’")
  signal(error ("Unable to find theme file for ‘emacs-morrowind’"))
  error("Unable to find theme file for `%s'" emacs-morrowind)
  load-theme(emacs-morrowind t)

  funcall-interactively(eval-expression (load-theme 'emacs-morrowind t) nil nil 127)

Thanks!
