Jonathan Wannstedt

Inventor & Owner of ChromaVue

ChromaVue started as a very personal problem: I needed a way to work safely and accurately in low-voltage wiring while living with color vision deficiency. Traditional tools and "one size fits all" solutions weren't enough, so I spent years experimenting with calibration, custom test patterns, and opponent-hue training approaches until I found a combination that produced a measurable change in my own test performance.

As I continued using the approach, I found some color-dependent wiring tasks easier in my own work. That personal experience motivated me to develop the idea beyond a personal workaround and share it with others. Out of that work, ChromaVue was born—a platform designed to make structured, data-driven color training accessible to others who want to better understand and train their color-discrimination performance.

Behind the scenes, I've focused on more than just clever visuals. ChromaVue is built around consistent testing flows, careful tracking of progress, and a strong emphasis on privacy and security. I want you—and, where applicable, your clinic or school—to feel confident that the system is both trustworthy and actively maintained, not a "black box" you never hear about again.

If something isn't working as expected, if you're confused about a result, or if you simply want to share an idea or concern, you can contact me directly. I personally review incoming messages and will work with you to resolve issues or point you in the right direction.
