I write an application that uses a 4 or 5 different colors to indicate 
various important conditions. There are so many varieties of color 
blindness that I decided to make the colors user-settable. That way each 
user can set up a palette that he or she can easily differentiate (even 
if it's only different shades of gray).

I use a few other colors as "eye candy" and chose to not make those 
user-settable. No complaints so far (except mild griping from a few 
folks who like to tweak everything).
