This is working for me for now (it's only lightly tested, fails gracefully if the numbers are too high, fails ungracefully if you give too few arguments, and uses features in bash new to me (hey, been away for awhile), so not sure if they are standard or new... with that out of the way:

Now I can do things like echo "$(c_grey 15)I'm light Grey$(c_clr)" and
echo "$(cb_rgb 5 0 0)Red$(cb_rgb 0 5 0)Green$(cb_rgb 0 0 5)Blue$(c_clr)"

At any rate, hope this helps someone.
