Yes, if there is no change in luminosity or a very subtle one (the threshold is 3:1), than it’s considered to be just a change of color, which is a violation.

But again: make the focus clearly visible.

The standards WCAG, ATAG... are a consensus of minimal demands.

For real world users it’s better to have stronger visual cues, than a luminosity change and/ or color.

Even for people without disabilities this can be really hard to see while quickly tabbing through a page.

And I also consider it a lost chance for a great design solution, that might support the corporate design.

I never understood why so few designers take this chance to give a website a nice little extra...

There are great examples for beautiful and accessible focus styles.

Ok thanks, I’m with you I think. So if links change colour when focused, then as long as the contrast is greater than 3:1 that is sufficient as focus indication and then it use wouldn’t fail ‘use of colour’ because it isn’t just a colour change, because it’s also a sufficient enough contrast change that this is an additional visual cue?

What if the contrast change is less than 3:1? Would this then fail use of colour?

Thanks

Maybe an example helps. Quite a lot of men cannot see a difference between red and green. But they can see a difference between dark and bright.

Actually anybody who can see at all, can recognise a difference between brightness and darkness.

Even some officially blind people (less than 4% of sight on the better eye) can recognise it (of course not on a single word, that is a too subtle change)

Oh ok, so what is the difference between a change in contrast and a change in colour then? Sorry for the confusion, I just want to make sure I’m clear on the difference.

I’m not sure, if I understand you right, but to keep it simple: a change in contrast ist not a change in color. If the change in contrast ist 3:1 or more, than it is considered as a sufficient visual cue

I know why I’m confused..

If a link has no visual cue on focus it would fail AA focus visible. But if it does have a visual cue, but that is a colour change, that seems higher fail - A use of color, even though it seems as though some sort of visual cue is better than no visual cue at all...

It seems like the lower fail (AA) is if nobody can perceive a focus indicator, and then a higher fail (A) for if some people can pervieve a focus indicator but others can’t.

Subject: Links on focus

Hello,

If the focused state of a link is only indicated by a colour difference relative to its original state does this fail 1.4.1 Use of colour? G183 seems to imply that it does but this also encompasses links being a different colour from surrounding text so I wasnt sure?

1.4.11 non-text contrast is a bit vague on this, again it mentions colour difference of links with surrounding text with respect to 1.4.1 but doesnt say much about links in focus and 1.4.1.

Is a change in relative luminance between focused and unfocused links enough of a visual cue that the colour difference is sometimes acceptable as a focus indication?

Or is a change in colour to indicate focused and unfocused links never acceptable? In which case it would fail use if colour and focus visible? Or does it just fail focus visible because the focus state doesnt count as the sort of information covered by use of colour?

Thanks,

Sarah
