Re: Non-text contrast comment

> What would the effect be if we said there must be a 3.1 contrast ratio against adjacent colors; and if there is a border, then a 3.1 contrast against it and the colors on either side of it?

We would be mandating a particular design style and I suspect be looking at an AAA criteria.

It would also be very difficult to do, if you had a button on a white background then the border must be dark, then the inner background must be light and the text dark (or vice versa).

You could not have a row of button like in the example using different colours.
