Frequently Asked Questions
How does it work?
The colorblindness simulations in the Huetility colorblind Simulator are based on the human vision system. We model how the human eye perceives color based on the retina's cone responses and adjust the model to reflect how the world looks to someone who is colorblind based on their modified cone responses.

Who is it intended for?
The app is intended to be used by people who want to learn about colorblindness. It's ideal for parents wishing to see how their child sees the world or for designers who want to understand how colorblind people perceive color. If you are colorblind or you know someone who is colorblind then this app is great for helping to explain and understand colorblindness.
