Abstract
A wetness indicator material may be used on a substrate to form a wetness sensor. The sensor may show either the presence or absence of an aqueous-based fluid or water-containing medium, such as vaginal fluid or urine in a personal hygiene article. The wetness sensor may be incorporated into the article. The wetness indicator material includes a standard colorant that does not change color when wetted. The standard colorant increases the range of hues exhibited by the wetness indicator material.
