finally found the answer here from this helpful site!
There is a free (or nearly free) program called “xv”. One web site is
http://www.trilon.com/xv It is written by one of those dying breed of
UNIX programmers who just *loved* UNIX and programming and sharing it.
His web site is enjoyable because some of his passion comes through.
With xv, you can make a postscript file from a Consed window. Then
you can print the postscript file on a color printer.
However, since some Consed windows are mostly black (Aligned Reads
Window and Traces Window), this uses up a lot of toner and is
difficult to read. So go to the Consed Main Window, pulldown the
‘Options’ menu and release on ‘General Preferences’. Scroll down to
“Make light background in Aligned Reads Window…” and click on “Do it
now”. Dismiss any Aligned Reads Windows or Traces Windows and then
bring them back up. You will notice the light background. A few
other things (traces colors and thickness) are also customized for
making color prints.
