Web Accessibility Audit and Accessible Color Tools

Review WCAG issues, screen-reader order, contrast failures, color-vision risk, and accessible palette choices in one hub for website and UI accessibility workflows.

This hub focuses on the accessibility checks teams usually need before shipping a page, component, or design refresh: audit HTML, inspect reading order, review screenshots for low-contrast regions, compare color pairs, and build safer palette choices for real interfaces.

Why this hub exists

Accessibility review is rarely one check. Teams usually need markup audits, reading-order inspection, contrast testing, and color-vision simulation together before a page feels safe to publish.
Keeping WCAG checkers, screen-reader simulation, screenshot heatmaps, and palette contrast tools in one place makes it easier to move from a rough finding to a concrete fix.
The included HTML, color-code, and component samples give users a fast way to test alt text, contrast pairs, and UI component patterns before they run the tools on live product pages.

FAQ

What can I do in this hub?

You can audit HTML or live pages for WCAG issues, simulate reading order, inspect low-contrast UI regions, compare color pairs, and review whether a palette stays readable for different users.

Who is this hub for?

It is useful for frontend developers, designers, QA reviewers, content teams, and anyone who needs to make websites or components easier to read, navigate, and understand.

How should I start?

Start with the general accessibility checker or report generator, then move into screen-reader simulation and color-specific tools when you need to confirm reading order, contrast, or color-vision safety.
