Thanks Rachael

For those wanting to explore this more the SC proposal is here

https://docs.google.com/document/d/1WhZAbswvPHs7A3stfqM_ATsaBHPeGbHtARcmaKMck1U/edit?usp=sharing

and the text is

"Each active user interface component provides a visual indicator which 
conveys its purpose. Where the visual indicator is a underline or an 
outline shape, the visual indicator has a contrast ratio of 3:1 with at 
least one adjacent color."

This is certainly an important cognitive accessibility concern and 
overlaps with [at least] these Patterns

* Make it clear what are controls and how they should be used
* Support personalization of symbols and controls

But as Alastair points out

"we would have to be able
to answer the question “What is an appropriate visual indicator?” for
any user-interface control."

The tension is in ensuring we can define suitable indicators that are 
clear to everyone and yet allowing designers free choice that does not 
limit the required accessibility. If we are too prescriptive we will get 
a lot of push back and miss the intent. If we are to relaxed there is a 
danger the intent of the SC is subverted. Tricky.

This question is somewhat an open ended and general across Patterns and 
cognitive SCs as they impact content design. Another broad question is 
what should be explicitly covered by an SC and what is best moved to 
personalisation, perhaps with an outline in SC itself. This uncertainty 
is raised in this SC text.

These questions are likely to require significant discussion before 
distillation into an firm SC. We may need a lot of examples to ensure we 
have all cases covered if we cannot find a simple way to define for all 
controls.

So unless we can easily answer Alastair's question or avoid it by 
invoking personalisation with some clearly defined limits for this SC I 
think the 2.2 timescales is going to be very hard to meet.

Can anyone think of a way to resolve this?
