> *Interpretation:*
>
> My interpretation of the SC, and what I believe that the WG intended is
> that:
>
> 1.        Visual information that is important to identifying the state
> or existence (boundary) needs to be at least 3:1.
>
> 2.        All visual aspects of a UI Component at not required to meet
> 3:1, only if it is required to identity the state or existence of the
> control.
>
> 3.        For some components, text that is 4.5:1 is entirely sufficient
> to meet the requirements of 1.4.11.
>
> a.        Are we requiring a full boundary around links (which are UI
> Components)? I don’t believe so.
>
> b.        Are we ok with a set of tabs like in example #9 above, or does
> each tab need a full boundary to indicate the click area? I believe so.
>
> 4.        If a color is less than 3:1, you need to pretend that it
> doesn’t exist at all and assess whether the component passes based on other
> information.
>
> a.        Compare the same set of tabs in example #9 and consider whether
> it is less accessible if the non-active tabs have a pale color background.
>
> 5.        Hover is covered, but not relative to the component’s own
> non-hover state. What is covered is that the hover state needs to meet the
> 3:1 ratio for any non-text content. This means that if there is an icon in
> a button that fades out when hovered, it would fail (just like is the case
> for 1.4.3 if text in a hovered button fades on hover).
>
>
>
> *With my interpretation the examples above are rated:*
>
> 1.        Pass
>
> 2.        Borderline fail – perhaps an uncomfortable pass?
>
> 3.        Pass
>
> 4.        Pass

> 5.        Pass

> 6.        Pass

> 7.        Pass

> 8.        Pass

> 9.        Pass

> 10.        Pass

> 11.        Pass
>
> 12.        Pass – the right side example passes easily. The left side,
> with the underline border is, I think, an uncomfortable pass. Like a lined
> paper form, people can figure out the rough size of the fields by proximity
> and spacing, so one line is minimally sufficient.

> 13.        Pass

> 14.        Is interesting – this example clearly fails, but if the
> control was properly associated with the label would that help since that
> creates a clickable region that has sufficient contrast and then the
> control becomes more visible when focused because of the focus rectangle or
> input carat?
>
> 15.        Fail – the contrast for the boundary is particularly
> significant in this situation.
>
> 16.        Fail – the contrast for the selected state. This is an example
> of communicating information by color alone and the contrast doesn’t make
> up for the color.
>
> 17.        Fail - Similar to #14. Some might argue that if the label is
> properly associated that this makes the text label and image part of one
> control and therefore ok, and we should be clear about that in a technique
> or failure.

> One of the comments we received requested that we implement a requirement
