* Tao theme

 Two uncoloured color themes for Emacs: tao-yin and tao-yang.

** Installation

Tao in [[https://melpa.org/#/tao-theme][MELPA]]

`M-x package-install tao-theme`

or alternatively:

`M-x package-install-file tao-theme`

** Customization

 By default ~tao-theme-scale-fn~ is ~tao-theme-golden-scale~, and produce following colors:

#+BEGIN_EXAMPLE
 #FCFCFC #FAFAFA #F6F6F6 #F1F1F1 #E8E8E8 #DADADA #C3C3C3 #9E9E9E #616161 #3C3C3C #252525 #171717 #0E0E0E #090909 #050505
#+END_EXAMPLE

 You can change that: 

 - ~tao-theme-scale-fn~ should return 16 2-digit numbers (/tao-theme-golden-scale/)
 - ~tao-theme-scale-filter-fn~ scale filter (/by default filter (< it #x05) (> it #xFC)/)
 - ~tao-theme-use-height~ (/nil/)
 - ~tao-theme-use-sepia~ (/nil/)
 - ~tao-theme-use-boxes~ (/t/)
 - ~tao-theme-sepia-depth~ (/10/)
 - ~tao-theme-sepia-saturation~ (/1.03/)

** Integration 

~(defun tao-palette () (tao-theme-golden-grayscale-yin-palette))~, then you can use ~tao-with-color-variables~ macro:

#+BEGIN_SRC emacs-lisp 
(tao-with-color-variables tao-palette
  (progn
    (setq
      hl-paren-colors (list color-14 color-11 color-9 color-7 color-6)
