Color Blindness Simulation

Color Blindness Simulation tools allow designers to view their designs through the lens of different types of color blindness, such as red-green, blue-yellow, or monochrome blindness. This simulation helps ensure that color choices do not hinder accessibility for users with visual impairments and ensures that critical information is conveyed through design elements beyond just color.

Roughly 1 in 12 men has some form of color blindness — meaning if your product uses color as the only way to convey status (red = error, green = success), a meaningful chunk of your users can't tell them apart. Running a color blindness simulation takes 5 minutes and can catch issues that would otherwise generate confused support tickets and accessibility complaints.

Many dashboards use red/green charts to show positive vs. negative metrics — a color blindness simulation would immediately reveal these are indistinguishable for red-green colorblind users, prompting the addition of icons or patterns alongside the colors.
