Well, one that I have gives a warning message that says it can't handle
color 24 and substitutes 16 for such lines. But I wasn't sure if that
was correct behaviour. Another one that I've played with quietly
accepts such lines, but appears to always use black as the edge color
within a subfile if 24 is given as the main color, regardless of what
the main color was in the calling file. So I don't know what to think.

This possibility had occurred to me, but I didn't want to make that
assumption.
But if these occurrences are just a mistake, would it be a bad thing to
just treat lines "1 24 ..." as if it were "1 16 ..." (as the program I
mentioned above does)?
