#xres-theme
A theme that queries xrdb in order to dynamically create an Emacs theme. This works for both GUI and terminal Emacs, preserving translucent bg-color, if present.
Currently unsuitable for inclusion into Spacemacs Contrib as it assumes a 24bit color escape code patched Emacs.
If you're looking for something similar just for GUI Emacs, check out Xresources-theme on MELPA.
