You mentioned that Emacs will find a color that is the closest to the RGB value 
I am referring to the list of colours that Emacs uses to color-match the 
arbitrary RGB user-value supplied.Supposedly there is a list of colours that 
emacs uses for matching against.  Is the full list defined by
color-name-rgb-alist.  Or are they supplied by hardware calls, or additional 
ones with no specific name?
