Very cool tip!! In my case, however, my .cshrc file might be a better 
choice since I don't use bash, and of course the syntax is different.  As 
someone else pointed out the above will break scripts that use grep.  A 
moment or two of Googling turned up another option.  If one uses 
--color=auto, it will colorize output going to a terminal but won't if the 
output is piped to another command or redirected to a file.  The downside 
is that with --color=auto output piped to less -r doesn't get colorized. 
I'm sure there's a creative way to keep from breaking existing scripts and 
still be able to view colorized output via less.

After another moment of Googling, for yellow, use:

setenv GREP_COLOR '1;33'

or your shell's equivalent.
