I can't reproduce this.

The most likely problem is that some of your windows are not
color windows. Unless you specify a true value for the :color-p
initarg when you create a window, either explicitly or by including
it as a default initarg in the class definition (as color-dialog does),
you will get a non-color winodow which can display only 8 colors.


; This creates a window that can display only 8 colors
(make-instance 'window)

; This creates a color window
(make-instance 'window :color-p t)
