See what color blind people see using your iPhone
Huetility Simulate is a tool to see how things look to someone who is color blind. It uses the best scientific methods available to simulate the different types of color blindness, including the most severe forms of red-green and blue-yellow color blindness.
"The perfect tool for anyone wanting to learn about colorblindness"
- Donald McIntyre, author of: Colour blindness, Causes and Effects
The tool will be of great interest to the colorblind, their parents, spouses and friends. It will be found of value by professionals where an understanding of color blindness is necessary for their work, such as graphic designers, opticians and accessibility specialists.
Features
- See how 300+ million colorblind people perceive color.
- Compare the different types of colorblindness using 28 sample images.
- See the world as a colorblind viewer using your iPhone's camera.
- Learn about the different types of color blindness and their impact.
- Identify the colors that may cause the colorblind problems.

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.
Why don't you simulate all types of colorblindness?
The scientific models for simulating the severe (dichromatic) forms of colorblindness are well developed whereas the milder types of colorblindness (anomalous deficiencies) are more difficult to model; they are varied and less stable. We focus on modeling the severe types as they require no calibration and provide a good indication of the less severe types of colorblindness.
