Call For Consensus — ends FridayJune 23rd at 1:00pmBoston time.

The Working Group has reviewed and approved a Success Criterion for 
inclusion in the Editor’s Draft: "User Interface Component Contrast 
(Minimum)" with the goal of obtaining additional input external to the 
working group.

SC TEXT:

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:

 1. *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.
 2. *Inactive:*Disabled or otherwise inactive user interface components
    are exempt from this requirement.
 3. *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.

not been discussed already and feel that those concerns result in you 
“not being able to live with” this decision, please let the group know 
before the CfC deadline.
