If I have interpreted your question correctly, you want to read
the lines 

	color = red
	size = big

into your script and have each line read into a variable.


To do this, use the construct:

	while read DEFINITION; do
		echo "$DEFINITION";
		.
		.
		.
	done;


BTW, you can also read from a specific file by redirecting the
input to the read command like this:

	INPUTFILE="some_file";

	while read DEFINITION <$INPUTFILE; do
		echo "$DEFINITION";
		.
		.
		.
	done;
