WCAG 3 / APCA contrast checking

[tobimori]

WCAG 3 will use a new color contrast method called APCA (Advanced Perceptual Contrast Algorithm).
This is way more accurate as it uses the perceptually correct contrast.

It would be cool if this is toggable via a Field property.

That's a good idea 👍

The repo for code is https://github.com/Myndex/apca-w3

It also available as an NPM package:

npm i apca-w3

And we have a forum here if you have any questions.

There’s a very good article about the flaws of the old algorythm that predates APCA: https://blog.datawrapper.de/color-contrast-check-data-vis-wcag-apca/
