Colleagues:

This is a Call for Consensus (CfC) to the Accessible Platform
Architectures (APA) Working Group on a proposed specification review
comment to the CSS Working Group.

*	Background Information

This CfC is issued pursuant to a resolution logged by APA during its
regularly scheduled teleconference of Wednesday 27 July and logged at:
https://www.w3.org/2016/07/27-apa-minutes.html#ResolutionSummary

The proposed comment below was previously posted to public-apa at:
http://lists.w3.org/Archives/Public/public-apa/2016Jul/0040.html

*	Proposed Comment

The Accessible Platform Architectures (APA) Working Group requests
addition of the following section to the specification 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.

*	ACTION TO TAKE

This CfC is now open for objection, comment, as well as statements of
support via email. Silence will be interpreted as support, though
messages of support are certainly welcome.

If you object to this proposed action, or have comments concerning this
proposal, please respond by replying on list to this message no later
than 23:59 (Midnight) Boston Time, Tuesday 2 August.
