[Israel.pm] text coloring

[Yossi Itzkovich]

Hi
 
Is there a way to give colored text in a standard way ?  We are doing it
here with:
$red="\033[31m";
$black="\033[30m";
$yellow="\033[35m";
 
and it looks OK in xterm/dtterm, but vi and excel show no color but the
gibberish text.
 
Is there a way to do it ?
