WhoCanUse is a tool designed for web developers and designers to help them understand how color contrast affects people with different visual impairments. It provides a comprehensive analysis of color combinations based on the Web Content Accessibility Guidelines (WCAG), giving users insight into how various visual impairments impact the perception of their design.

Key Features

• Analyzes color contrast and provides a grade based on WCAG guidelines
• Simulates various visual impairments, including color blindness, cataracts, glaucoma, and low vision
• Evaluates the impact of situational events like direct sunlight or night mode on color visibility
• Allows users to input custom foreground and background colors, text size, and style to test their design's accessibility

How It Works

1. Enter your desired foreground and background colors, along with text size and style.
2. WhoCanUse calculates the color contrast ratio and assigns a grade according to WCAG standards.
3. The tool simulates how different visual impairments affect the perception of your color choices.
4. Review the results to ensure your design is accessible to a wide range of users.

Benefits

This tool humanizes the data by providing estimates of the population affected by different visual impairments, making it easier to understand the real-world impact of your design choices.
