;; Version: 0.1
;; Keywords: color theme
;; URL: https://github.com/mssola/soria

;;; Commentary:
;;
;; This is a color theme based on xoria256 (vim.org #2140) but with some
;; modifications here and there with colors from openSUSE's guidelines
;; (http://opensuse.github.io/branding-guidelines/).

;;; Credits:
;;
;; FEI Hao for the xoria256 port (https://github.com/suxue/xoria256-emacs).
;; This theme is *largely* based on this port.
;;
;; Kelvin Smith for the port of the Monokai theme to Emacs
;; (https://github.com/oneKelvinSmith/monokai-emacs). I've taken a *lot* of
;; inspiration from its source code.
;;
;; I've adapted some of the color IDs with this gist:
;;  https://gist.github.com/MicahElliott/719710
