Re: CFC Add User Interface Component Contrast (Minimum) to Editors Draft

Hey James,

While we wait for the minutes...take a look at the proposed SC text for
User Interface Component Contrast (especially the notes at the end).  Let
me know if you have any questions.

*PROPOSED 1.4.14 User Interface Component Contrast (Minimum)*
Essential visual identifiers of user interface components have a contrast
ratio of at least 4.5:1 against the immediate surrounding color(s), except
for the following situations:


   - *Thicker:* A contrast ratio of at least 3:1 is required where the
      minimum width and height are at least 3 CSS pixels, for the essential
      visual identifier.
      - *Inactive:* Disabled or otherwise inactive user interface components
      - *User agent control:* The color(s) of the user interface component
      and any adjacent color(s) are determined by the user agent and are not
      modified by the author.


*Notes*


   - Examples of essential visual indicators of user interface components
      may include (a border, edge, or icon), current value (such as non-text
      visual indication of aria-valuenow on a slider) and current
state (such as
      selection indicator, focus indicator) or other essential visual
indication
      (which do not rely on color alone).
      - *Under consideration*: simplify this Success Criterion by setting
      the minimum color contrast requirement to 3:1 and removing any need for
      measuring thickness.
      - *Under consideration:* will review to see if it is possible to
      combine with proposed WCAG 2.1 SC 1.4.11 Graphics Contrast.
