Attachment: Accessibility Inspector results for the button and options

Since these buttons do not have any visible text always, NVDA mouse tracking will not read the text, which is a known issue with NVDA mouse tracking.

The options are rendered as expected in the Accessibility tree (refer to the screenshot attached), with an informative labels. So the lack of on-hover announcement, in this case, is the NVDA bug.

What we could do is to add an on-screen text next to color option circles, so there is an on-screen text (that is included in the option markup) - this should be announced by the NVDA.

I'll triage it as access-s4 since this is not a delightful pattern in any case, but yet the issue is not as severe and is largely dependent on the assistive technology software, unless we'll change the visual appearance.
