Wrong colors in GIF

[Neil Parks]

Tried to view the attached GIF with Arachne, and it looked awful.  It is
supposed to be a directory tree as seen in a winbloat file manager, but
the dark blue background makes everything pretty much unreadable.

The same GIF looks exactly right when viewed with the ancient (1991)
Cedar Island GIF viewer 1.0.
