If X-gal is not added to the agar selection medium all of the colonies would be white.

X-gal is an organic compound used to test the presence of an enzyme, β-galactosidase. X-gal is colourless, but in the presence of β-galactosidase, it becomes blue because of the cleavage of the β-glycosidic bond inside its structure.
