Comment Type: technical
Summary of Issue: graphics contrast is unmentioned (except as exceptions)
Comment (Including rationale for any proposed change):
None of the contrast requirements in guideline 1.4 apply to graphics, except where specific types of graphics are specifically exempted.

This fails to account for primarily graphic applications, such as maps, traffic indication, wayfinding tools, and many others.

People have a primarily visual interaction with the Web. Where graphics are presented as a key part of an interface, even given a text-based alternative, many people will rely on the graphics.

It is therefore important to require sufficient accessibility of graphics content for visual users.

Proposed Change:
Add requirements for appropriate visual contrast in graphics used to provide functionality of a site or application.
