I have some 8-bit color bitmaps I would like to display under NeWS
(via the readcanvas routine). It appears, however, that the NeWS
colormap is static and that readcanvas just selects the closest
color.

Unfortunately, the closest color algorithm makes my images look
interesting, but not in the way I would like.

Is there any way of fiddling the colormap? It doesn't have to
be particularly portable.

[I am running NeWS 1.1 on a Sun 3/60 under SunOs 3.4]

As a footnote, it seems that Sun were very shortsighted if there is
no way to get the colors you really asked for. Lots of real world
applications need just that (in particular, mine does :-).
