About Who Can Use
What Is Who Can Use?
Who Can Use is a free accessibility tool that provides insights into how color contrast impacts those with visual impairments. It fits within the accessibility category of design tools, enabling designers and developers to evaluate color combinations during the UI design and development workflow. By simulating various visual conditions, Who Can Use helps ensure digital interfaces meet contrast requirements for broader usability.
What Who Can Use Does
- Simulates color contrast visibility under conditions like color blindness and low vision.
- Displays real-time previews of text and UI elements as perceived by users with visual impairments.
- Calculates contrast ratios between foreground and background colors based on standard guidelines.
- Offers adjustable sliders to test different color pairs and their accessibility impact.
- Provides visual representations of common visual impairments such as deuteranomaly and protanomaly.
- Supports quick checks for compliance with WCAG contrast standards.
How Who Can Use Can Be Used
- During initial UI design, designers input brand colors to verify readability for users with visual impairments before finalizing palettes.
- In web development workflows, developers test button text, links, and form elements to identify low-contrast issues early.
- For mobile app prototyping, teams simulate low-light or high-glare scenarios affecting color perception.
- When auditing existing websites, accessibility specialists scan multiple pages to flag non-compliant color schemes.
- In collaborative design reviews, teams share Who Can Use previews to discuss and adjust colors for inclusive design.
