Re: Graphics contrast updates

Hi Everyone,

I’ve cleared all the comments (i.e. responded or updated the request) for Graphics Contrast:
https://github.com/w3c/wcag21/pull/100


The last change was to add an ‘essential’ caveat to cover things like exams or medical graphics which have to match what you would see more realistically. I took the text structure from 1.1.1 so hopefully it is a reasonable WCAG approach.
