There are two things you need to check before relasing your program:
1) issue *FontList in a TaskWindow
   run the program, cause it to change font a few times, quit the
   program and do that a few times
   issue *FontList again and the Use counts should be as before
2) change screen mode from a square pixel mode to a rectangular pixel
   mode (one above the divider line in the Display manager, e.g., 1280
   by 480)
   do the fonts still look correct?

Changing the colours is different for outline font icons. That should 
not come as a surprise since the outline font handle is stored in the 
very same bits as the foreground and background colours. At a guess, 
your routine just changes these bits, but that only works for system 
font icons (bit 6 clear) and in your case overwrites the font handle. 
For outline font icons, you need to change the font colour values 
stored in the validation string's F command.
