+This is the list of common problems.
+Emacs 20.7: Some faces are created using copy-face; these faces are
+not printed correctly using M-x color-theme-print. They will have
+(nil) in their spec. M-x customize-face has the same problem.
+(copy-face 'bold 'new-bold)
+(color-theme-spec 'bold)
+ => (bold ((t (:bold t))))
+(color-theme-spec 'new-bold)
+ => (new-bold ((t (nil))))
+XEmacs 21.1: Some faces are defined using a certain font instead of
+of the correct attribute. They will have (nil) in their spec.
+M-x customize-face has the same problem.
+(color-theme-spec 'bold)
+ => (bold ((t (nil))))
+XEmacs 21.2 and up, Emacs 21: Not compatible with the custom-theme
+mode. It should be easy to transform the color-theme source into
+custom-theme source, however.
+If you are running XEmacs, then only foreground and background color
+of the default face and only the background color of the text-cursor
+face will used. This is due to the fact that these three pieces of
+information are stored as frame parameters in Emacs.
+If you are running XEmacs, variables cannot have a frame-local
+binding. Therefore, if color-theme-is-global is set to nil, the
+variable settings in a color theme are ignored.
+Using Emacs and a non-nil value for color-theme-is-global will
+install a new color theme for all frames. Using XEmacs and a non-nil
+value for color-theme-is-global will install a new color theme only
+on those frames that are not using a local color theme.
+If your system does not define the color names used, you will get the
+error "undefined color". See the output of `list-colors-display' for
+a list of colors defined on your display.
+The :box, :height, and other new attributes will be honored in Emacs
+21, but when you print such a color-theme on Emacs 20 or XEmacs 21,
+the information will get lost. So don't do that. Furthermore,
+customizing these faces may end up showing you a lisp expression
+instead of the real widgets on Emacs 20 or XEmacs 21 because these
+attributes are not understood.
+:inverse-video handling differs in Emacs and XEmacs. We therefore do
+away with it. When printing a color-theme, the inverse-video
+attribute should be handled correctly without ever appearing in color
+themes. For maintenance, the following might be usefull for
+:background "\([^"]*\)"\(.*\):foreground "\([^"]*\)"\(.*\) :inverse-video t
+:background "\3"\2:foreground "\1"\4
+In XEmacs 21.1, some of the face tests don't work. Example:
+(custom-face-bold 'bold) returns nil on my system. A bug report was
+Emacs 20 users will loose with new color themes, because these will
+set the colors of the default face only, leaving frame background
+untouched. In Emacs 20, the colors of the default face and of the
+frame could be changed independently. In Emacs 21, this is no longer
+true. New color themes will not be made backwards compatible.
+This release was superficially tested with Emacs 21.x/22.x and XEmacs 21.4.

+Sharing your current color setup:
+Use `color-theme-submit'. If you have already invested time in
+customizing Emacs faces, please consider sharing your current setup.
+Make sure that color-theme.el is in your `load-path'. Type M-x
+load-library RET color-theme RET to load all the functions. Type M-x
+color-theme-submit RET and mail the result to the maintainer of this
+package (see above for mail addres).
+If you want to make sure that all your customization was exported,
+type M-x list-faces-display RET to get a list of all faces currently
+defined. This is the list of faces that `color-theme-print' uses.
+Installing a color theme:
+Make sure that color-theme.el is in your `load-path'. Type M-x
+load-library RET color-theme RET to load all the functions.
+The main function to call is color-theme-select. Type M-x
+color-theme-select RET. That creates a Color Theme Selection
+buffer. Press RET or `i' on a color theme to install it for the
+rest of your session.
+If you want to install the color theme as soon as Emacs is started
+up, read the description of the theme you like and remember the
+name of the color theme function. Press `d' on a color theme in
+the Color Theme Selection buffer to read the description. Assuming
+you like the Gnome2 theme, you'll find that the function to use is
+called `color-theme-gnome2'. Add the following to the end of your
+.emacs (removing the leading `;;').
+(require 'color-theme)
+Changing menu colors:
+In Emacs 21 on X, you can set the menu colors and font using the
+menu face. Example for your .emacs file:
+ (set-face-font 'menu "7x14")
+ (set-face-foreground 'menu "white").
+If are using X, you can set the menu foreground and background using
+a resource file, usually .Xdefaults or .Xresources. Usually
+.Xdefaults is used when you start your session using a display
+manager such as xdm or gdm. .Xresources is usually used when you
+start X directly via a shell script such as startx. If you set
+Emacs*Background and Emacs*Foreground in such a resource file, the
+foreground and background of Emacs including the menu will be set.
+If your .emacs then loads a color theme, the foreground and
+background are changed -- with the exception of the menu. There is
+no way to manipulate the menu foreground and background color from
+elisp. You can also set more specific menu resources for Emacs in
+the resource file. Here is a sample entry for your resource file:
+ Emacs*Background: DarkSlateGray
+ Emacs*Foreground: wheat
+Creating your own color theme:
+Use M-x customize-face and customize the faces. Make sure to "Set
+for Current Session" -- you don't want to save these using custom!
+When you are done, call M-x color-theme-print to produce the elisp
+code required to recreate your theme. Better yet, use M-x
+color-theme-submit to mail it to the maintainer. That way it will be
+added to future versions of color-theme.el.
+For more information on the elisp format of a color theme, start with
+the documentation of `color-theme-install' using C-h f
+When your color theme is just a variation of an existing color theme,
+take a look at `color-theme-robin-hood' in order to see an example of
+how to do it. Essentially you want to call all the parent color
+themes before installing your changes. For all but the first parent
+color theme, you need to make sure that `color-theme-is-cumulative'
+is bound to t. If you don't do that, users that set
+`color-theme-is-cumulative' to nil will only install your changes
+without the parent color themes.
+Making a color theme work for both Emacs and XEmacs:
+Once you have printed the color-theme, you can make sure it looks
+similar in both Emacs and XEmacs by running
+`color-theme-analyze-defun' on the printed theme. This function
+will check for missing faces for the other editor...
