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

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…
