[Athen] color contrast vs. color difference

[Howard Kramer]

Please excuse the cross-posts.

I recently ran the Juicy Studios Contrast Analyzer and found 1 color
contrast issue for the AHG home page <http://accessinghigherground.org/>
(this seems to be a case of a css color setting that does not actually
appear on the page) but a number of color difference issues. The latter is
not specified in WCAG 2.0 as far as I can tell. Is color difference an a11y
issue? Or should the focus be luminosity ration (“color contrast”)?
