Correct - If the only distinguishing characteristic is color (HUE) then it would fail. However, please note the LIGHTNESS is not the same a hue. So if the links are in a color that is VISIBLY MUCH LIGHTER or DARKER than the surrounding text then it is possible that the links can be distinguished without color — and it would pass. For example The word link in this sentence is visible whether you can see color or not. The word link in this sentence is visible whether you can see color or not. Of course it is not as visible as with color - but the SC does not prevent it. In fact I think there might be a technique talking about this — or that discusses this. Ah here it is G183: Using a contrast ratio of 3:1 with surrounding text and providing additional visual cues on focus for links or controls where color alone is used to identify them On Apr 28, 2014, at 7:56 AM, Adam Solomon <adam.solomon2@gmail.com> wrote: > Thanks for the response, Andrew. > What if you didn't have the proper contrast and also didn't have any other cue then this would fail 1.4.1, right? > Example: a paragraph of text where two words in the paragraph are a link, like: > "This is the time for all good men" (where the words good men are actually a link, and there is no color contrast with the surrounding text) > And what if the link had the same color as the surrounding text - that might not fail because all users are at an equal disadvantage (since there is absolutely no cue that this is a link)? > > > On Mon, Apr 28, 2014 at 3:26 PM, Andrew Kirkpatrick <akirkpat@adobe.com> wrote: > Adam, > > Color contrast is a AA issue, so it doesn’t matter if the text is in an image or is regular text, the contrast is a AA issue. > > > > 1.4.1 speaks to conveying information with color, such as “click on the green button” but you can still meet 1.4.1 with poor contrast because by not relying on color alone you’d need to include other information. For example, “click on the green button that says ‘go’!”. It is possible to have text that is very low contrast on that button, and that is ok for 1.4.1, but would fail 1.4.3. > > > > AWK > > > > From: Adam Solomon [mailto:adam.solomon2@gmail.com] > Sent: Monday, April 28, 2014 12:25 AM > To: WCAG > Subject: contrast for images of text > > > > Would images containing text which don't have the proper contrast ratio fail at single A? I only see 1.4.3 (which is AA) mentioning the issue of contrast. I would have thought that images of text should fail at single A since the user agent has no way of overriding the css background and foreground color for these images?1.4.1 mentions the use of color to convey information and would seem a likely candidate to fail such an image, yet no mention is made there regarding images of text. > > Thank you for any feedback > >
