Ninety-six percent of people have normal color vision and have little understanding of how the other four percent of people with color blindness see the world. Color blindness simulations using digital image transformations can provide an approximation but without the impact of a real-world experience.
Enter the Color Blindness Simulator - I created this device for EnChroma as a demonstration aid for normal color-sighted people to understand the vision of people with color blindness, and to show the operation of the color blindness-assistive glasses.
By combining blue and yellow quasi-monochromatic light at high intensity, the simulator causes objects to appear nearly dichromatic (two-colored) even under broad-spectrum ambient lighting. When a person puts on EnChroma glasses, the effect is reversed and trichromatic color vision is restored.
The simulator was a popular booth activation at trade shows and events, helping the company to engage with the audience and create a memorable experience.
