Brad, thanks for these suggestions.  'clawsker' sounded very promising,
but I found that there's no MacPorts version of it, and that it depends
on some things also not available (AFAICT) on MacPorts.  Dependencies  
include
    make, sed, install, gettext and pod2man
I can do very rudimentary things on a Mac, but unfortunately building
a Linux program on a Mac isn't one of these.  If you or someone could
point me to relevant instructions I might be able to carry them out. 

The instruction 'grep -R color ~/.claws-mail' showed the file 'clawsrc'
had many entries for "color", and I'll play around with it for a bit to
see what I can modify. 

At the moment, tho, I'm stuck because when I try to start 'claws-mail',
instead of it starting I get the Terminal message 

  Xlib: connection to ":0.0" refused by server
  Xlib: No protocol specified 

  (claws-mail:72561): Gtk-WARNING **: cannot open display: :0.0 

My '~/.profile' already has 

  # To run X11 apps, we need:
  export DISPLAY=:0.0
  # ...and to use X11 as the graphics window server with 'gnuplot',
  export GNUTERM='x11' 

and I was able to start 'claws-mail' previously, so I'm not sure what
happened.  I'll re-start and try again.
