I've been building this tool off and on for about a year while trying to learn React (around other side projects and a fulltime gig).
It's a tool that brings attention and understanding to how color contrast can affect different people with visual impairments.
The Web Content Accessibility Guidelines (WCAG) covers a wide range of recommendations for making Web content more accessible. Just a tiny part of making the web more accessible is accommodating for those with a form of blindness or low vision.
The standard grading system is a great start, but I thought I'd try to humanize the people who are affected by the different grades.
Let me know if you have any feedback, questions or would like to contribute! Thanks!
