[css-color] Test result indication accessibility

[matatk]

This comment is from the APA WG and relates to our review of CSS Color Module Level 5.

This is quite possibly a bug in a library you're using, though I couldn't find any pointers after a brief search relating to WPT.

There's a low contrast difference between the two sections of the pie charts. This is particularly apparent in §4.

Suggestion: use techniques similar to those from Figure 21 in the Understanding WCAG SC 1.4.11 document, i.e. (1) separating the segments; (2) using more contrasting colours; and/or (3) using hollow and solid segments to ease differentiation.

Thanks. These inline pie-charts are generated by Bikeshed, and thus affect all CSS specifications and indeed all Bikeshed-generated specifications which reference Web Platform tests.

So I'm going to open a new issue over there.
