ICCCM specifies a COLORMAP_WINDOWS property that you can set with
a list of the windows containing colormaps that you want the window
manager to pay attention to.  Window managers have to deal with this
list somehow - mwm provides a colormap cycling function to allow the
user to sequence through the colormaps in the list with the press of
a button.

Here's the ICCCM excerpt:

WM_COLORMAP_WINDOWS

  The WM_COLORMAP_WINDOWS property, of type WINDOW, on a top-level 
  window is a list of the the IDs of windows that may need 
  colormaps installed that differ from the colormap of the top-
  level window.  The window manager will watch this list of windows 
  for changes in their colormap attributes.  The top-level window 
  is always (implicitly or explicitly) on the watch list.
  
  See Section 4.1.8 for the details of this mechanism.
