Do not use watch
... When you use watch programs can detect they're not writing to a terminal and then strip the color. You must use specific program flags to keep the control codes there.
If you don't know the flags or there isn't you can make a poor's man watch by:
while sleep <time>; do clear; <command>; done
It will have a bit of flicker (watch works "double buffered") but for some stuff it is useful enough.
You may be tempted to make a double buffered poor man's watch using
while sleep <time>; do <command> > /tmp/file; clear; cat /tmp/file; done
But then you'll hit again the "I am not writing to a terminal" feature.
