An absorbent article includes a liquid permeable bodyside liner, an outer cover, and an absorbent body located between the bodyside liner and the outer cover. The absorbent body comprises at least one colorant. The colorant, when wetted with a liquid, becomes visible so as to identify the presence of the liquid. The colorant may also detect substances in the liquid. The colorant can detect small volumes of liquid and volumes of liquids deposited outside the target area.
