Re: SC for 'real' text over a busy background image

Another option is to have a two or more pixel - halo like - contrasting
color right behind/underneath the text (and on top of the busy background)
- as is often done in parrallel s rilling situations for 1.4.3 conformance

If the background is in motionat all, this calls in 2.2.2, stopping at a
logical places and ensuring that those stopping points meet the 1.4.3
contrast requirements.

the problem with “readability” as a category is that it covers both
“Perceivable” and “Understandable”

If Readability is to be used in any future document — you will either need
to abandon   “Perceivable”,  “Understandable” ,  etc.   unless you break it
into
“Sensory Readability”  and “Cognitive readability” .


Also, it is interesting but some people associate “readability” only with
visual reading.    Readability of an audio recording does not make sense to
them (e.g. cognitive readability is not recognized to all if there is no
"visual readability”  component)

Comprehensibility
Readability
Clarity of perceivability
Understandability

all get confounded  — with some people including comprehension in
readability and others not —  esp if the content is non-visual.
 Readability of a recording doesnt make sense but readability of its
transcript does — and the will say readability of the transcript is both
visual and wording but readability of the recording makes no sense to them…

contrast, a better fit. It still doesn't explicitly address the issue of
legibility, that may not be due to contrast issues.


SC 1.4.3 is what we have at the A/AA level to address this.  Perhaps
readability is a topic for the next WCAG.  Also of note, there has been
some discussion in the LVTF about the difference between legibility and
readability, etc.

One of the LVTF, if they haven't started looking at this already.

Thanks

I'm working with a client and finding text (real text) that is
displayed over a busy background image that obscures its legibility.
Currently I don't see a clear SC for this kind of problem and it seems
to just sit somewhere under the principle that content must be
perceivable. The closest that I see is 1.4.5.
Am I missing something?


1.4.3 ?
