Thanks for the detailed description of your script. It keeps amazing me
how many things an awk script can do in a couple of lines.<br>

scale 0-255 to 0-100 and add a % sign. r.colors will do the rest.
r=
g=
b=
RULE="`echo $EIGHTBIT | awk '{print $1 / 2.55}'`% $r:$g:$b"
-> if $EIGHTBIT=255 then $RULE becomes "100% r:g:b"

Really a good tip -- will implement it right away.<br>
