case use instead of if else

Hi,
I'm writing a script where the requirement is of the sort
Code:
if echo $x | grep $a > /dev/null
then
COLOR1
elif echo $x | grep $b > /dev/null
then
COLOR2
..
..
fi

I want to replace this with case esac.
color to be changed based on $a $b .... a big list
also $x changes for each line of the file.
Smilie

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
