I have a PICT displayed in a window. The PICT is made up of say 16
different colours.

I want to highlight ONE of those colours while shading/hiding (pretending
the rest aren't there doesn't work for me) the rest.

Think of it as a road map if you like. I want to display only one road
while hiding all the others. Oh, the road maps (not really road maps) can
be widely variable in colour and size so you never see the same road twice
(unless the wife points out your lost)...

Question : is there an easy way to do this? Masking out colours or
something like that? Just a shove in the right direction would be
appreciated.
