Thanks for the reply,  It seems we were both halfway there.  you set
the foreground, but in order for it to actually be used (i.e. line be
red rather than black), it's gotta be alloc'd too.

So my question about Color's being Copy friendly still stands,  as
does my question about 'automagic-color' widgets.

Basically what I'm thinking is pretty much this (allowing for typos &
missing #includes)

http://www.koziarski.org/GColorManager.C
http://www.koziarski.org/GColorManager.h

Any problems with that code?  or am I needlessly duplicating work
available elsewhere?
