Draft Draft Draft

APA requests addition of the following section to this specification
to css color module level 4
https://www.w3.org/tr/css-color-4/

Accessibility Impact Statement

Content authors should be mindful of requirements on color
contrast as expressed in WCAG 2.0 Success Criterion 1.4.3:
http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html

. See also :
https://www.w3.org/WAI/perspectives/contrast.html

It is particularly important to be mindful of this requirement when a
transparency is present because automated measurement is not available
to quantatively and correctly judge whether sufficient contrast is being
provided, thus requiring application of informed human judgement on a
case by case basis.
