Where did you get the info from?

The percentages are sourced from both colour-blindness.com and Vision Australia. P.S. You're both the best, thankyou ✌️

Your maths is off, it doesn't add up to 100%...?

Good eyes! (haha) The population data provided are estimates for individual impairments, and don't cover the vast amount of visual impairments in the world. This is to give you not just an understanding of how color contrast affects different people but also who it can affect.

I'm fascinated by how this works, can you tell me more?

Of course! There's a few stages to get to this point. First we figure out the contrast between two HEX values. For this we're using a plugin called Chroma.js - this does the heavy lifting for us.

What does a failing grade mean?

The grading uses a combination of color contrast, text size and text weight. A fail simply means that the color combination offers some visual strain to the person seeing it and should be avoided if possible.

Can I help contribute?

Absolutely! Feel free to fork the repo and submit a PR with any helpful additions or changes.GitHubSponsorCreated & maintained by@CoreyGinnivan
