Hi @AutoSponge, here are some notes I took about these issues, which I hope will be helpful for us to come to an issue we could post.
Here's what I see as next steps...
What do you think on the above? If I've captured it well, could you enumerate the use cases, and maybe we workshop a comment from there?
In relation to https://github.com/w3c/csswg-drafts/issues/9970
It may be helpful to have a "sticky" feature and a "greater contrast" algorithm.
For example, if I have #6161FF
as a background color white (4.5:1) and black (4.66:1) both conform to current specs. The author may have a preference:
IMO, max should restrict the color to the max requested. For example, on a black background, white text reaches 21:1 luminance ratio. But if I requested a 15:1 max (with a base of white on black background) for people with migraines and astigmatism, then I should get something like #D9D9D9
. Maybe this works more like a clamp? But this only works in terms of the WCAG calculations. It means nothing to APCA calculations.
Also, since fillColor, color, and icons are a thing, we need to have ways of clamping at 3:1 on the min side and preferring that over a more aggressive 4.5:1. This is useful for a secondary call to action element.
