Question

Update:

Note that this thread does not applyt o recent versions of Emacs (24+). Emacs now comes with it’s own powerful color theming system (e.g. see a review here) that does not required loading the external package color-theme .

I have the following code snippet in my .emacs file, where I defined a few aliases that allow me to switch conveniently between a couple of color themes using short extended commands:

(require 'color-theme)            
(eval-after-load "color-theme"   
  '(progn                        
     (color-theme-initialize)    
     (color-theme-aalto-light))) 
                                                                                                                                      
;; Aliases to color-themes, e.g. 'M-x a' switches to color-theme-hober

(defalias 'a 'color-theme-hober)
(defalias 'b 'color-theme-aalto-light)

Now, when Emacs loads, it displays the color-theme-aalto-light theme properly, and, when I M-x a to change to color-theme-hober, that works too.

The problem is when I try to change the color theme back again to color-theme-aalto-light. Some color faces remain in the old color-theme while others are changed to the new color theme. I have tried with different color theme combinations with no luck (the color faces are not always fully updated, regardless of the color-themes I switch between). Any thoughts?

This is a known bug in ‘color-theme’ package. If that feature is important for you, consider upgrading to trunk (future emacs-24.1), it natively supports changing themes (M-x customize-themes).
