The Outlaw
See the web through the eyes of someone with red-green color blindness. A status dashboard uses only color to indicate problems - can you tell what is broken?
Wanted For
About 8% of men and 0.5% of women have some form of color vision deficiency. When websites use color alone to convey meaning (red for error, green for success), these users miss critical information.
Before You Ride
This simulation uses a color matrix filter to approximate protanopia (a form of red-green color blindness). Actual color vision deficiency varies between individuals and this is only an approximation.
You can exit the simulation at any time by pressing Escape or clicking the exit button.
