WhoCanUse is a straightforward tool that shows how color contrast affects people with different visual impairments. By entering foreground and background colors, users can see how these combinations look to individuals with color blindness, cataracts, or low vision. The tool also calculates contrast ratios and checks them against Web Content Accessibility Guidelines (WCAG) to help assess the accessibility of your color choices.
Created by Corey Ginnivan, WhoCanUse takes a human-centered approach by showing what percentage of the population is impacted by specific visual impairments. This makes it easier for designers and developers to make thoughtful decisions and create more inclusive designs. The tool even accounts for real-world scenarios, like viewing a screen in direct sunlight or using night mode, ensuring readability in various conditions.
