Website Accessibility Checker Tool
Analyze web pages to identify color accessibility issues and improve the user experience for all visitors. Enter any URL to preview how your website appears under different color vision conditions.
What This Tool Does
The Website Accessibility Checker analyzes web pages to help you identify color accessibility issues that might affect how visitors experience your site. By entering a URL and selecting a color vision simulation type, you can preview how your website appears to people who perceive colors differently. This tool focuses on helping creators understand color contrast problems, readability challenges, and design elements that might not work well for all users. Rather than replacing comprehensive accessibility audits, it serves as a practical starting point for improving your website's inclusive design.
The checker processes web pages and applies scientifically based color transformations to simulate various types of color perception. This approach helps designers and developers spot issues with color-dependent navigation, insufficient contrast ratios, and visual elements that rely solely on color to convey information. By testing your website through different color vision conditions, you can make informed decisions about palette choices, text legibility, and overall usability. The tool emphasizes design accessibility improvements rather than medical assessments, keeping the focus on creating better user experiences for everyone who visits your site.
Why Website Accessibility Matters
Making websites accessible ensures that your content reaches the widest possible audience, regardless of how they perceive colors or interact with digital interfaces. When websites prioritize accessibility, they become easier to use for everyone, not just people with specific vision characteristics. Clear color contrast improves readability on mobile devices in bright sunlight, while well-structured interfaces help users navigate more efficiently. Accessible design practices create better experiences across different devices, lighting conditions, and user preferences, which ultimately benefits your entire audience.
Beyond improving user experience, website accessibility supports better search engine optimization and demonstrates professional attention to quality. Search engines favor websites with clear structure, readable text, and proper semantic markup, all of which overlap with accessibility best practices. Sites with good contrast ratios and logical layouts tend to perform better in search rankings while also serving users more effectively. Investing in accessibility testing during the design process helps you catch and fix issues early, when changes are simpler and less expensive to implement. This proactive approach creates websites that work better for all visitors while supporting your business goals through improved usability and reach.
How to Use the Website Accessibility Checker
Test your website's color accessibility in just a few steps:
- Enter a website URL: Type or paste the web address you want to test. You can use full URLs like "https://example.com" or just "example.com" and the tool will add the protocol automatically.
- Select a color vision type: Choose which color perception condition you want to simulate from the dropdown menu, including red-green, blue-yellow, or other variations.
- Click Analyze Website: The tool loads the web page and applies the selected color vision simulation, showing you how visitors might experience your site's colors.
- Review the results: Examine the simulated view to identify areas where color choices might cause confusion, reduce readability, or make navigation difficult.
Important: This tool provides a preview to help identify potential accessibility issues. No data about your website is stored or transmitted beyond loading the page for display. The checker is designed for testing, educational purposes, and design improvement rather than formal compliance certification.

Frequently Asked Questions
What is a Website Accessibility Checker?
A Website Accessibility Checker is a tool that analyzes web pages to identify design elements that might create usability challenges for different audiences. In the case of color accessibility checkers, the tool simulates how websites appear under various color vision conditions, helping designers spot contrast issues, color-dependent navigation, and readability problems. These tools focus on the visual and structural aspects of accessibility, examining how color choices, layout decisions, and design patterns affect user experience. Unlike comprehensive accessibility audits that test against detailed standards, this type of checker provides a quick visual assessment to guide design improvements and identify obvious issues that need attention.
Does this tool guarantee full accessibility compliance?
No, this Website Accessibility Checker does not guarantee full compliance with accessibility standards like WCAG. The tool serves as a helpful starting point for identifying color-related accessibility issues by simulating different types of color perception, but comprehensive accessibility involves many factors beyond color alone. Full WCAG compliance requires testing keyboard navigation, screen reader compatibility, proper HTML semantics, alternative text for images, and numerous other technical requirements that this visual simulator does not assess. Think of this checker as one tool in a larger accessibility testing toolkit rather than a complete solution. It helps you improve color accessibility specifically, which is an important component of inclusive design, but professional accessibility audits remain necessary for sites that need to meet formal compliance standards.
