“Not that one, Mom,” said Ted. “I don’t want that one. I’m not putting it on my hands. Buy this one.” Eva sighed. Had she been this picky as a kid? Was this what her mother had meant when she’d said that Eva would understand someday? “There’s nothing wrong with it, Ted,” she said. “What reason could you possibly have for not liking this hand sanitizer? They’re the same.” Ted took a deep breath. He was trying as hard as he could to be patient. Why didn’t his Mom get it? “That one was yellow last time,” he said. “It’s not supposed to be yellow. There’s something wrong with it. I don’t want to put it on my hands.” Eva looked at her watch. Ted’s little sister would be done with dance in 12 minutes. This wasn’t the time to be arguing in Walgreens. “Okay,” she said. “Fine. We’ll get the other one. Let’s go.”
Color consistency is an important facet of quality control for manufacturers of hand sanitizer. While a customer may not be aware that they are looking for a particular color of sanitizer, they are likely to notice if the product is not the color they expect it to be, compromising saleability and damaging brand reputation. As such, color measurement is an integral part of product quality control, helping manufacturers ensure their product meets customer expectations.
