;;; Commentary:
;; A collection of (almost) grayscale Emacs themes. A lot of the code and
;; concepts were inspired by [@cryon](https://github.com/cryon)'s [Almost Mono
;; Themes](https://github.com/cryon/almost-mono-themes). Mostly what I did is
;; tweaking the color slightly to fit my tastes. Huge thanks to him!
