I'm not sure how I mistakenly gave the impression that I don't think 
"color-blindness" is a disability. It is.

What I've tried to get across is that the solution to the accessibility 
engendered by that disability, as with all other such conditions, is to 
find generalizable principles for addressing solutions via 
guidelines/checkpoints - not to address individual situations in our document.

The notion of being aware of problems people have with color/contrast in 
Web materials is addressed by counseling authors to remain aware/alert that 
presentational means associated with providing content must be "minable" by 
users through their agents. The semantics must be discoverable.

We tell authors to consider *all* presentational elements without needing 
to specify at certain levels of granularity any specific ones. Rather than 
"attend to color/contrast" we say "attend to presentational elements" 
(which of course include 

Presentation/style inevitably (almost) convey information and the 
perseverance through transformational processes of that information is what 
we must strive to ensure.
