Why the nail-polish concept still mattered
If the nail polish never became a mass-market product, was the idea a failure?
Not necessarily.
Innovation does not always produce the product people originally imagine.
Sometimes the first concept is valuable because it forces researchers to ask better questions.
Undercover Colors helped popularize a broader conversation about personal safety technology.
It demonstrated how chemical sensing could potentially be incorporated into an everyday object.
It encouraged discussion about whether safety products should be discreet, portable and easy to use.
And it showed the power of interdisciplinary thinking.
The four students were engineers, but their idea sat at the intersection of materials science, chemistry, product design, entrepreneurship, public safety and social awareness.
NC State's account of the project shows how the university's entrepreneurship ecosystem helped the students transform a senior design project into a startup. The university also emphasized that the company was only one part of a much larger effort to combat sexual violence, alongside prevention, survivor services, education and cultural change.
That broader perspective is arguably more important than the nail polish itself.
Technology can empower—but it cannot carry the entire burden
There is an understandable appeal to products that promise greater personal control.
A person going out for the evening may feel more confident knowing that they have a way to check a suspicious drink.
A small device can fit into a purse, pocket or keychain.
A test that takes seconds may feel easier to use than laboratory equipment.
But technology should complement—not replace—social responsibility.
Friends looking out for one another matter.
Bars and clubs having responsible safety procedures matter.
Bystander intervention matters.
Clear communication about consent matters.
Accessible medical and forensic services matter.
And holding perpetrators accountable matters.
The CDC's approach to sexual-violence prevention emphasizes changing environments and social norms, not simply asking individuals to protect themselves from violence.
That distinction is particularly important because an excessive focus on personal precautions can unintentionally shift responsibility toward potential victims.
The question should never be:
“What could she have done differently?”
It should be:
“Why did someone choose to harm another person, and what can individuals, institutions and communities do to prevent that harm?”
A safety device can help with the second question, but it can never answer it by itself.
What happened to the original dream?
The original vision of Undercover Colors was remarkably memorable.
A bottle of nail polish.
A normal night out.
A quick touch of a fingernail to a drink.
And a color change that could potentially warn someone before they drank.
But the actual journey was much more complicated.
The four students created the idea as an engineering project. The concept attracted international attention. Their startup received investment and continued developing detection technology. The team experimented with color-changing compounds and nail-based detection. Eventually, however, the nail polish was abandoned as a consumer product because of its limitations.
The company then moved toward a dedicated testing device.
SipChip became the tangible result of that evolution, launching commercially in 2018.
Patent records also document the company's continued work on wearable and liquid-detection technologies, showing that the original concept was part of a broader effort to develop portable substance-detection systems.
So the viral nail polish story was not exactly wrong.
