I just tried out color-theme with emacs24.
It seems the code on http://orgmode.org/worg/org-color-themes.html is not
quite compatible with elpa packages.
Here is what I used instead.
;-----------------------------------------------------------
; To easily cycle between different colour schemes using the F4 key
(require 'color-theme)
(require 'cyberpunk-theme)
(require 'leuven-theme)
(require 'tangotango-theme)
(require 'zenburn-theme)
(setq color-theme-is-global t)
(setq my-color-themes (list
'cyberpunk
'leuven
'zenburn
'tangotango
))
(defun my-theme-set-default () ; Set the first row
(interactive)
(setq theme-current my-color-themes)
(load-theme (car theme-current) t))
(defun my-describe-theme () ; Show the current theme
(interactive)
(message "My color theme: %s" (car theme-current)))
(defun my-theme-cycle () ; Set the next theme
(interactive)
(setq theme-current (cdr theme-current))
(if (null theme-current)
(setq theme-current my-color-themes))
(load-theme (car theme-current) t)
(message "My color theme: %S" (car theme-current)))
(setq theme-current my-color-themes)
(setq color-theme-is-global nil) ; Initialization
(my-theme-set-default)
(global-set-key [f4] 'my-theme-cycle)
;------------------------------------------------------------
